+
+Section 2 – Scope.
+
+     a.	License grant.
+
+          1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:
+
+               A. reproduce and Share the Licensed Material, in whole or in part; and
+
+               B. produce, reproduce, and Share Adapted Material.
+
+          2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.
+
+          3. Term. The term of this Public License is specified in Section 6(a).
+
+          4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a)(4) never produces Adapted Material.
+
+          5. Downstream recipients.
+
+               A. Offer from the Licensor – Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.
+
+               B. Additional offer from the Licensor – Adapted Material. Every recipient of Adapted Material from You automatically receives an offer from the Licensor to exercise the Licensed Rights in the Adapted Material under the conditions of the Adapter’s License You apply.
+
+               C. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.
+
+          6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).
+
+     b.	Other rights.
+
+          1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.
+
+          2. Patent and trademark rights are not licensed under this Public License.
+
+          3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties.
+
+Section 3 – License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the following conditions.
+
+     a.	Attribution.
+
+          1. If You Share the Licensed Material (including in modified form), You must:

+
+                    v.	a URI or hyperlink to the Licensed Material to the extent reasonably practicable;
+
+               B. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and
+
+               C. indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License.
+
+          2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material.

+
+Section 4 – Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:
+
+     a.	for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database;
+
+     b.	if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material, including for purposes of Section 3(b); and
+
+     c.	You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.
+For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.
+
+Section 5 – Disclaimer of Warranties and Limitation of Liability.
+
+     a.	Unless otherwise separately undertaken by the Licensor, to the extent possible, the Licensor offers the Licensed Material as-is and as-available, and makes no representations or warranties of any kind concerning the Licensed Material, whether express, implied, statutory, or other.

Where a limitation of liability is not allowed in full or in part, this limitation may not apply to You.
+
+     c.	The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.
+
+Section 6 – Term and Termination.
+
+     a.	This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.
+
+     b.	Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:
+
+          1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or
+
+          2. upon express reinstatement by the Licensor.
+
+     c.	For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.
+

+title: "MultiMiner Austria -- Mapping Hochfilzen"
+subtitle: Überblick für die geologische Kartierung
+lang: de-AT
+---
+
+# Einleitung
+Dies soll als eine Einführung für die Vorbereitung der geologischen Kartierung dienen. Es werden die zu kartierenden Gebiete definiert und ein kurzer geologischer Überblick präsentiert. Das Untersuchungsgebiet wird in einen modernen regionalgeologischen Rahmen gestellt und die für die Kartierungsarbeiten relevantesten Gesteine vorgestellt.
+
+Als Basis für eine tiefer gehende Einarbeitung seien die Erläuterungen zu Blatt 122 Kitzbühl [@Heinisch2015] und vor allem die dortige reichhaltige Literaturliste erwähnt. Einen geologischen Überblick über die Magnesitlagerstätten bei Hochfilzen gibt bspw. @Vavtar1976.
+
+Magnesitmineralisationen sind aktuell in der Spielbergdolomit-Gruppe und im Dolomit-Kieselschiefer-Komplex (s. u.) bekannt und die bekannten Lagerstätten, wie Weißenstein und Bürgl, liegen im Hochhörndler-Komplex [@Heinisch2015].\
+Zu den Magnesitlagerstätten im Untersuchungsgebiet sein erwähnt, dass es über deren Alter und deren Genese eine bis in das 19. Jahrhundert zurückreichende Diskussion mit bedeutenden Meinungsverschiedenheiten gibt. Das Alter reicht hier vom mittleren Silur über Variszisch bis Alpidisch und das Spektrum der Genese von primär-sedimentär, synsedimentär über frühdiagenetisch bis metasomatisch und zur Magnesiumzufuhr gibt es ebenso die unterschiedlichsten Vorstellungen [@tollman1977geologie].\
+Zu dieser Thematik siehe auch @sec-MgsGenetix.
+
+
+## Lage des Untersuchungsgebiets
+Geographisch befindet sich das Untersuchungsgebiet etwa fünf bis sieben Kilometer südwestlich von Hochfilzen -- siehe @fig-AOI_Overview. Es liegt zum größten Teil im Bundesland Tirol und ein kleiner Teil liegt im Bundesland Salzburg.
+
+![Lage des Untersuchungsgebietes -- rot markiert (Grundkarte: basemap.at)](Figs/Overview__AOI_inAustria.pdf){#fig-AOI_Overview}
+
+## Kartenblätter
+Die zu kartierenden Gebiete betreffen die Blätter 122 Kitzbühl [@Heinisch2003] und 123 Zell am See [@Heinisch1995]. Zu ersterem Kartenblatt sind Erläuterungen [@Heinisch2015] vorhanden. Die Grenze der beiden Kartenblätter ist im Untersuchungsgebiet die, hier etwa Nord-Süd orientierte, Fieberbrunner Ache. Flächenmäßig liegt der Großteil der zu bearbeitenden Gebiete auf Blatt 122.\
+Nennenswerte "Blattrandstörungen" sind zwischen diesen Blättern im Untersuchungsgebiet nicht bekannt und hier auch nicht von größerer Bedeutung, da kein Kartierungsgebiet die Blätter überlappt. Wichtige Lithologien haben auf den Kartenblättern unterschiedlichen Nummern, sind aber in etwa gleich benannt.
+
+## Fragestellungen
+Das grundsätzliche Thema und die Fragestellung der Kartierungsarbeiten ist die Magnesitmineralisation. Entsprechend liegt der Fokus auf geologischen Parametern von denen anzunehmen ist, dass sie für die Magnesitmineralisation relevant sein könnten. Von Bedeutung erscheinen hierfür, ohne Anspruch auf Vollständigkeit, Kontakte zu den Nebensteinen, Unterschiede in den Korngrößen, Störungen, \dots\
+Es darf nicht außer Acht gelassen werden, dass das Untersuchungsgebiet im Zuge dieses Projekts, mit Methoden der Erdbeobachtung (earth observation, EO) und Fernerkundung (remote sensing, RS) bearbeitet wird und die Ergebnisse der Kartierungsarbeiten mit den Erkenntnissen dieser Methoden verknüpft werden. Insofern soll bei der Geländearbeit auch beachtet werden was ein Satellit bzw. Drohne "sieht" und somit bspw. nicht nur schöne Aufschlüsse untersucht werden, sondern auch verwittertes Gestein.
+
+
+
+## Praktisches
+An dieser Stelle noch ein paar Worte zur praktischen Geländearbeit und deren Vorbereitung:
+
+* Online sind die Regionen und Gebiete mit unterschiedlichem Kartenmaterial unter <https://ardigeos.geologie.ac.at/mumimap> dargestellt.
+* Die Kartierungsgebiete können durch den Link <https://rhea.geologie.ac.at/index.php/s/rUqqImMlXdzGAUl> als GeoPackage bezogen werden.
+* Die beiden Kartenblätter können durch das Tethys Research Data Repository, der Geosphere Austria, über folgende Links als PDFs und als GeoPackages bezogen werden:
+  * GK 122 Kitzbühl: <https://doi.tethys.at/10.24341/tethys.53>
+  * GK 123 Zell am See: <https://doi.tethys.at/10.24341/tethys.54>
+* Die Geologischen Karten der Republik Österreich 1:50.000 können über folgende WMS/WMTS-Verbindung in GIS-Programme als Raster-Layer eingebunden werden: <https://gisgba.geologie.ac.at/arcgis/services/image/AT_GBA_GK50/ImageServer/WMSServer?request=GetCapabilities>
+* Als Koordinatensystem zur Markierung von Geländepunkten ist WGS84, EPSG:4326, zu verwenden. Dies ist jenes Koordinatensystem, das auch von GPS-Geräten verwendet wird.
+* Die Positionen von GPS erfasste Punkten sind, vor ihrer Weiterverwendung, noch mit einem GIS-Programm und Satellitenbildern (bspw. der Orthofoto-Layer von basemap.at) zu überprüfen und im Bedarfsfall zu korrigieren.
+* Strukturmessungen sind in (dipDirection, dip)-Wertepaaren anzugeben -- so wie sie Gefügekompasse nach Clar liefern -- und nicht wie im angloamerikanischem Raum zu Teil noch üblich in (strike, dip)-Wertepaaren.
+* Die Verwendung von 10\%iger Salzsäure zur Unterscheidung von Magnesit und Dolomit hat sich nicht bewährt. Diese kann trügerisch sein, da zum Teil auch Aragonit anwesend sein kann. Eine makroskopische Identifikation der Karbonate ist geeigneter.
+* Die Probenbeschriftung soll nicht auf der Probe mit einem Permanent- oder Lackmarker erfolgen, sondern die Probe soll in einen Beutel gegeben werden und dieser ist zu beschriften. Der Grund ist eine evtl. Spektralanalyse an der Probe im Labor und durch Marker hinzugefügte Farben könnten diese Analyse erschweren oder verunmöglichen.
+* Für die Kartierung erscheint der Zeitraum Juni-Juli ideal, da hier meist eine stabile Wetterlage (v.a. Juli) vorherrscht und die Tage lang sind. Im August ist traditionell mit Niederschlag zu rechnen. Im September könnten sich abermals günstige Witterungsbedingungen ergeben, wobei die Tage zu dieser Zeit schon kürzer sind.
+
+
+
+# Regionen und Gebiete
+Die zur kartierenden Gebiete liegen in einem etwa West-Ost orientierten Streifen südlich von Fieberbrunn und Hochfilzen mit dem aktiven Abbau Weißenstein circa in der Mitte -- siehe @fig-mappingAreasOverview und @fig-mappingAreasOverview_GK. Zur (vorläufigen) Strukturierung ist dieser Bereich in drei Regionen und zugehörigen Gebieten aufgeteilt. Diese werden hier nun kurz -- von Ost nach West und mit abnehmender Priorität -- beschrieben.

+
+![Übersicht über die Kartierungsgebiete (Grundkarte: Geologische Karte Österreich)](Figs/MappingAreas__Overview__GK.pdf){#fig-mappingAreasOverview_GK}
+
+## Region Ost
+Liegt östlich des aktiven Abbaus Weißenstein und als einzige der Regionen auf Kartenblatt 123. Sie ist durch die ehemaligen Abbau Bürgl, im West, und Inschlagalpe, im Osten, begrenzt. In dieser Region lassen sich zwei Magnesitvarietäten ausmachen: Eine feinkörnige und eine grobkörnige.
+
+### Gebiet 1
+Östlich des ehemaligen Abbaus Bürgl bzw. die östliche Seite des Spielberggrabens. Dieses Gebiet sollte leicht erreichbar sein: Zufahrt via Burgeralm und Parkmöglichkeit dort und weiter. Nach Absprache mit den Grundbesitzern kann eventuell auch der Almweg zum Kleberkopf-Sattel benutzt werden.\
+Für Teile dieses Gebiets gibt es eine detaillierte Beschreibung und Kartierung durch @Riedler2010.
+
+     
+### Gebiet 2
+Das Gebiet um den ehemaligen Abbau Inschlagalpe. Hier ist eine gut aufgeschlossene Fläche westlich des ehemaligen Abbaus von großem Interesse. (Süd)östlich dessen ist das Gelände sehr steil und bewaldet -- da es aus betrieblichen Kartierungen bereits bearbeitet wurde, ist es nicht von primärem Interesse, sollte aber dennoch überblicksweise begangen werden.\
+Hier findet sich ein relativ grobkörniger Magnesit mit Null Porosität.\
+Zufahrt über das Schwarzleotal mit Parkmöglichkeit beim Schaubergwerk Leogang. Eventuell kann nach Absprache mit dem Wegobmann die Privatstraße hinter dem Schranken benutzt werden.
+
+
+### Gebiet 3
+Das ist noch ungenau definiert. Hier ist noch am Laserscan anzusehen ob man herauserodierte Härtlinge findet. Falls nicht ist die Südgrenze des Spielbergdolomits abzugehen.\
+Zufahrt über das Schwarzleotal mit Parkmöglichkeit beim Schaubergwerk Leogang. Eventuell kann nach Absprache mit dem Wegobmann die Privatstraße hinter dem Schranken benutzt werden.
+
+## Region Zentral
+Diese Region ist am östlichen Rand des Kartenblatts 122. Es ist das Gebiete westlich und nördlich um den Abbau Weißenstein.
+
+### Gebiet 4
+Ist ein Wandergebiet, es gibt unter anderem den Blumenweg und am “Grat” eine Art von “Klettersteig”.\
+Von großem Interesse ist hier ein Aufschluss von schwarzem Dolomit und speziell auch dessen Kontakte zum Nebengestein. Weiteres ist dies ein Gebiet in dem der Glemmtal-Komplex bzw. der Hochhörndler-Komplex nicht nur untergeordnet auftritt und deshalb hier mehr Metabasite vorzufinden sein könnten.
+
+### Gebiet 5
+Den etwa West-Ost orientierten "Grat" beim Lärchfilzkogel entlang bis hinunter in den Hörndlingergraben.\
+Parkmöglichkeit bei der Lärchfilzhochalm und im Hördlingergraben.
+
+## Region West
+Diese Region liegt direkt am westlichen Anschluss zu Region Zentral und auf Kartenblatt 122. 
+Diese Region ist für die Modellverifikation der earth observation (EO) und des remote sensings (RS) angedacht. Die EO soll erst Anhaltspunkte für etwaige Magnesitvorkommen liefern, diese im Anschluss aufgesucht werden.\
+Diese Region ist durch den Pletzerbach und seine Zuläufe, den Lengfilzenbach und Grubalm mit Sulztalbach, gekennzeichnet.
+
+### Gebiet 6
+Dieses Gebiet ist noch wenig bekannt. Magnesit ist als Rollstücke im Geschiebe des Pletzerbaches bekannt. Ihre Herkunft in Form von Aufschlüssen ist nicht bekannt und soll nach Möglichkeit geklärt werden. Im Norden des Pletzergrabens sind mächtige Spielbergdolomite aufgeschlossen. Speziell ihre Grenzen nach Süden sollen lokalisiert und bearbeitet werden. Das Gebiet ist Teil des Pletzergrabens und kartiert werden soll beidseitig des Pletzenbachs.\
+Dieses Gebiet hat die geringste Priorität und soll in Abhängigkeit von Möglichkeiten kartiert werden.
+
+
+
+# Geologischer Rahmen
+Auf den genannten Kartenblättern befindet sich das Untersuchungsgebiet in der Wildseeloder-Einheit $\subset$ Grauwackenzone $\subset$ Oberostalpin. Kleinräumige Kontakte zur Glemmtal-Einheit -- ebenfalls Grauwackenzone -- und den Nördliche Kalkalpen $\subset$ Oberostalpin könnten vorkomme.\
+
+Diese Nomenklatur geologischer Einheiten entspricht nicht mehr dem aktuellen Wissensstand. Nach moderner, tektonischer Nomenklatur ist das hier zu untersuchende Gebiet Teil der Staufen-Höllengebirge-Decke welche dem Tirolisch-Norischen-Deckensystem zugeordnet wird [@Schmid2004; @Heinisch2015; @Huet2019].\
+Eine tektonische Übersichtskarte der Ostalpen ist in @fig-TectUnitsofEasternAlps_afterSchmid gegeben und @fig-EAlpsTectUnits zeigt ein schematisches Diagramm der großen tektonischen Einheiten der Ostalpen und der Eingliederung des Tirolisch-Norischen-Deckensystems in diese Einheiten. Die paläogeographische Position des Ostalpins vom Kambrium bis in das Devon ist in @fig-PagGeo__AA__RockyAT skizziert.\
+Die lithostratigraphische Gliederung paläozoischer Gesteine innerhalb der Staufen-Höllengebirge-Decke [@Huet2019; @Huet2022] erfolgte in Anlehnung an die Erläuterungen zur GK 122 Kitzbühl [@Heinisch2015]. Es werden hierin vier Komplexe unterscheide, die variszischen tektonischen Einheiten entsprechen. Vom Liegenden in das Hangende sind dies folgende lithodemische Einheiten: Uttendorf-, Glemmtal-, Hochhörndler- und Wildseeloder-Komplex. Diese werden von permomesozoischen lithostratigraphischen Einheiten diskordant überlagert.
+
+Die Metamorphosegeschichte der Staufen-Höllengebirge-Decke ist bisher wenig erforscht. Im Allgemeinen wird davon ausgegangen, dass es eine Zunahme des Metamorphosegrades von Norden nach Süden gibt [bspw. @SchlaegelBlaut1990; @Heinisch2015; @Rantitsch2009]. Pauschal kann, für das Untersuchungsgebiet, von maximal grünschieferfaziellen Druck-Temperatur-Bedingungen ausgegangen werden: Etwa im Bereich von \SIrange{350}{400}{\celsius} und Drucken von mehr als \SI{3}{\kilo\bar} und weniger als \SIrange{4.5}{8}{\kilo\bar} [@SchlaegelBlaut1990; und dortige Referenzen].
+Im Detail scheint es jedoch schwierig, die Deformationen und Metamorphosen dem Variszischen oder dem Eoalpidischen Ereignis zuzuordnen [@Huet2019].\
+Aufgrund der Illit-Kristallinität, dem Grad der Grafitisierung, dem Vorhandensein von Chloritoid und dem Conodont Alteration Index (CAI) wird von einer Metamorphose in der (unteren) Grünschieferfazies im Zuge des (kretazischen) Eoalpidischen Ereignisses ausgegangen. \isotope[40]{Ar}/\isotope[39]{Ar}-Alter, aus Hellglimmer-Feinfraktionen, im Bereich \SIrange{115}{95}{\Ma} zeigen die Abkühlung der Gesteine der Staufen-Höllengebirge-Decke und deren Exhumation während dieses Ereignisses an [@Schuster_etal_2004; @Heinisch2015; und dortige Referenzen]. Diese Metamorphose wurde im Zuge der alpidischen Orogenese, im Oligozän bis Miozän, abermals durch einen advektiven Wärmetransport und zirkulierende Fluide schwach überprägt [@Rantitsch2009].
+Eine variszische Metamorphose ist im Untersuchungsgebiet nicht belegt; es wird jedoch von einer schwachen (unterste Grünschieferfazies) präalpidischen Deformation und Metamorphose ausgegangen [@Heinisch2015].
+Dies ist konsistent mit \isotope[40]{Ar}/\isotope[39]{Ar}-Datierungen [@Panwitz2006] an detritischen Muskoviten, die neoproterozoische Alter (im Bereich \SIrange{600}{800}{\Ma}) anzeigen. Die Schließtemperatur von Muskovit im \ce{Ar}/\ce{Ar}-System, \SI{390 \pm 50}{\celsius} [@Schaen2020], wurde somit seit dieser Zeit nicht (wesentlich) überschritten.
+
+## Anmerkung {.unnumbered .unlisted}
+Zu den Begriffen "Grauwackenzone" und "Nördlichen Kalkalpen" sei erwähnt, dass diese historischen Begriffe aus einer Zeit vor dem heutigen Verständnis des tektonischen Deckenbaus der Alpen stammen [@Schuster2015]. Man kann diese Begriffe wohl als geologische Einheiten verstehen – im Sinne, dass sie sich auf dafür charakteristische Gesteine beziehen. Sie sind aber keine tektonischen oder lithostratigraphischen Einheiten im engeren Sinne [@Huet2019].\
+Der Begriff Grauwackenzone beschreibt eine geographische Einheit [@Schuster2015] welche einen Ost–West orientierten Streifen paläozoischer Gesteine darstellt. Dieser ist mehrere hunderte Kilometer lang, reicht etwa von Schwaz in Tirol bis nach Niederösterreich an den Rand des Wiener Beckens und hat eine maximalen Breite von etwa \SI{25}{\km} [@Heinisch2015]. Aufgrund der räumlichen Zuteilung lassen sich die Westliche und Östliche Grauwackenzone unterscheiden.\
+Somit ist der Begriff Grauwackenzone – und die damit einhergehenden Untergruppen wie nördliche, südliche, westlich und östliche – als informeller Begriff ohne stratigraphische und tektonische Bedeutung zu sehen.

+# Lithologischer Inhalt {#sec-lithoContents}
+Lithologisch ist der, für die Untersuchungen hier besonders relevante, Wildseeloder-Komplex aus mittelordovizischem Metaignimbrit (Blasseneck-Porphyroid), oberdevonischen Siliziklastika und unterschiedlichen silurischen bis oberdevonischen Karbonatgesteinen (u. a. Spielbergdolomit-Gruppe) aufgebaut [@Heinisch2015; @Huet2019].\
+Vornehmlich an den südlichen Rändern der zur untersuchenden Gebiete können Gesteine des Glemmtal-Komplexes und des Hochhörndler-Komplexes auftreten. Der Glemmtal-Komplex umfasst größtenteils frühpaläozoische bis unterkarbonen Tonstein, Siltstein, Sandstein und Konglomerat mit einem turbiditischen Ursprung mit untergeordneten Einschaltungen von ordovizischen und devonischen Metabasiten und lokal auch Vorkommen von Blasseneck-Porphyroid und Karbonatgesteine [@Huet2019]. Der Hochhörndler-Komplex besteht aus einer siliziklastischen Matrix mit isolierten karbonatischen und magmatischen Elementen aus dem Wildseeloder-Komplex und dem Glemmtal-Komplex und er stellt wahrscheinlich eine Abfolge mit Olistolithen und/oder eine tektonische Zone dar [@Huet2019]. Der Gesteinsinhalt der benachbarten Komplexe liegt im Hochhörndler-Komplex überarbeitet vor.\
+
+In den Kartenblättern sind nur der Wildseeloder- und der Glemmtal-Komplex ausgeschieden. Diese stellen mit ihren spezifischen Lithologien unterschiedliche Fazies dar. Der Hochhörndler-Komplex ist implizit als eine "Übergangszone" -- in welcher die Lithologien der beiden anderen Komplexe vermischt vorkommen -- zu verstehen.\
+Für die praktische Geländearbeit lassen sich die Gesteine den Komplexen wie folgt zuordnen (mündl. Mitt. Benjamin Huet):
+
+Wildseeloder-Komplex
+: Mächtige Karbonate und Metaignimbrit, fast keine Basite, fast keine Pelite
+
+Hochhörndler-Komplex
+: Isolierte, kleinräumige Körper von Basiten, Karbonaten, Porphyroid in einer Matrix von Siliziklastika wie Tonschiefer, Quarziten, \dots\
+  In den Geologischen Karten ist der Hochhörndler-Komplex dadurch zu erkennen, dass Einheiten des Wildseeloder-Komplexes neben Einheiten des Glemmtal-Komplexes ohne Störung dazwischen liegen.
+
+Glemmtal-Komplex
+: Basite in Karbonaten und Siliziklastika
+
+
+
+Wichtige Lithologien werden hier kurz beschrieben und sind in stratigraphischen Gliederungen in @fig-lithoStrat_StaufenHoellen_Heinisch und @fig-LithStratModel_StaufenHoellen_Huet zusammenfassend dargestellt.
+
+
+## Blasseneck-Porphyroid
+Im Untersuchungsgebiet ist dieser Porphyroid beispielsweise am Wildseeloder mit einer bis zu \SI{600}{\m} mächtigen Abfolge anzutreffen [@Heinisch2015]. Er wurde mit dem, nach der steirischen Typlokalität benannten, Blasseneck-Porphyroid aufgrund von lithologischen Kriterien und seiner stratigraphischen Lage unter den Llandoveryschen[^Llandovery] Kalksteinen korreliert [@Hubmann2014].\
+Dieser Porphyroid werden als subaerische bimsreich Ablagerungen, aus einem pyroklastischen Dichtestrom, die in flache Meeresbecken gespült wurde interpretiert.  Der Vulkanismus wird als ein, \ce{SiO2}-reicher, alkalirhyolithischer bis rhyolithischer angesehen und der Chemismus legt – begründet durch den alkalirhyolithischen Charakter – ein extensionales Regime nahe. Somit könnte es sich um einen riftbezogenen Magmatismus gehandelt haben, der durch einen erhöhten Wärmestrom zu einer partiellen Aufschmelzung kontinentaler Kruste geführt hat [@Heinisch1981; @Heinisch2015].\
+Jüngere Untersuchungen mit U/Pb-Datierungen aus Zirkonen und Studien zur Zirkonsystematik durch @Blatt2013 zeigen Alter im Bereich von \SIrange{471}{461}{\Ma} und legen ebenso eine Interpretation eines kontinentalen Riftings nahe.\
+Als paläogeographische Position wird der Nordrand von Gondwana angenommen.

+
+## Spielbergdolomit-Gruppe
+Diese Gruppe bildet das Trägergestein von einigen Lagerstätten wie Siderit, Baryt (Schwerspat), Fahlerz und – hier von besonderer Bedeutung – Magnesit. Diese Dolomite stellen die wichtigsten Gipfelbilder im Untersuchungsgebiet und bilden einen zusammenhängenden Gebirgszug vom Kitzbühlerhorn über den Wildseeloder, das Spielbergerhorn bis zur Inschlagalpe. Die Typlokalität dieser Dolomite, das Spielbergerhorn [@Hubmann2014], ist eine der Grenzen des Untersuchungsgebiets (Region 2, @fig-mappingAreasOverview und @fig-mappingAreasOverview_GK).\
+Diese Gesteinsgruppe wird als eine silurisch-devonische Karbonatplattform [@Blatt2013] – die nunmehr dolomitisiert vorliegt – interpretiert. Eine Alterseinstufung von, wenngleich spärlichen und schwach metamorphen, Makrofossilienreste von Korallen, Crinoiden sowie gelegentlichen Conodonten legt einen Zeitraum der Ablagerung von Unter- bis Oberdevon für diese nahe [@Heinisch2015; und dortige Referenzen].\
+Aus dem Gestein und den Fossilienresten kann die typische Bildung einer Karbonatplattform mit Riffkomplexen und Lagune ableitet werden. Der Übergang zum Festland lässt sich aus Einträgen von tonig-sandigen Klastika, deren Einflüsse sich in höheren Teil verstärkt wiederfinden, erkennen. Die unterschiedlichen Fazies manifestieren sich im Dolomitgestein unterschiedlicher Ausprägung. Nach @Heinisch2015 lassen sich unterscheiden:
+
+Massenfazies -- Massiger Dolomit
+: Durch gelegentliche Relikte von Korallen wird dieser massige Dolomit als Riff-Fazies der Karbonatplattform interpretiert
+
+Bankfazies -- Gebankter Dolomit
+: Der Übergang der Massen- in die Bankfazies ist fließend und somit schwankt die Bankmächtigkeit von zwei Meter (seltener) bis Dezimeter (häufiger).\
+Diese Fazies bzw. dieser Dolomit überwiegt hinsichtlich der Häufigkeit des Auftretens die anderen Dolomite dieser Gruppe. Aufgrund der Mächtigkeit und der Ausdehnung wir durch diese Gesteine von einer bedeutsamen (devonischen) Karbonatplattform ausgegangen.\
+Sedimentstrukturen sind gelegentlich als Laminite erhalten, die als Überreste von Algenmatten aus dem Stillwasserbereich einer Lagunenfazies gesehen werden. Weiteres lassen sich gelegentlich Crinoidenreste erkennen, die einen Übergang von Riffschuttfazies zum Riffgebieten darstellen könnten.
+
+Flaserdolomit-Fazies -- Roter Flaserdolomit
+: Im faziellen Übergang zur Bankfazies treten dünnbankige gefärbte Zonen auf und es können bis zu Zentimeter mächtige Tonschieferlagen auftreten. Die rote Farbe der Flaserdolomite kann als einen äolischen Eintrag von Wüstenstaub gesehen werden.
+
+Dolomit-Sandstein-Folge
+: Es wechseln gebankte Dolomite mit Quarzsandsteinbänken und Tonschiefern. Auch innerhalb der Dolomite sind Quarzklasten festgestellt worden. Gemeinsam mit den Flaserdolomiten wird diese Folge als terrigener Sedimenteintrag eines Kontinentes interpretiert. Fazielle könnten diese beiden Dolomite den Übergang der Lagunenfazies zum Strandbereich darstellen.
+
+Insgesamt wird in der Spielbergdolomit-Gruppe eine küstennahe Flachwasserfazies am Gondwana-Nordrand gesehen [bspw. @Blatt2013; @Heinisch2015; und dortige Referenzen]. Eine Skizze eines solchen möglichen Ablagerungsraumes ist in @fig-rimmedCarbonatplattform gegeben.

+
+### Südfazies {#sec-suedfaz}
+Ein Begriff der in der (ältern) Literatur über das Untersuchungsgebiet immer wieder auftaucht ist die sogenannte "Südfazies". Dieser Begriff geht auf @Mavridis1969 zurück. Dieser gliedert die Karbonatgesteine, etwa im Bereich zwischen Wörgl im Westen und Bischofshofen im Osten [@Haditsch1970], zum ersten Mal in zwei Fazies: Die "nördliche Fazies" und die "südliche Fazies". Dies beiden Fazies wurden sowohl lithologisch als auch stratigraphisch unterschieden und durch eine etwas West-Ost orientierte Störung getrennt gesehen. @Mostler1970 sah auch eine "Dolomitbarriere" zwischen den nördlich gelegenen Spielbergdolomiten und der Südfazies. Für die nörliche Fazies wurde der Begriff Spielbergdolomit eingeführt und deren stratigraphische Reichweite wurde mit Emsium bis Eifelium (oberstes Unterdevon bis unteres Mitteldevon) festgelegt. Die südliche Fazies wurde als eine Abfolge von unterschiedlichen Dolomiten definiert (vom Liegende in das Hangende): Schwarzer Dolomit, hellgraue Dolomite und rote Flaserdolomite und hell- bis dunkelgraue grob spätige Dolomite. Die stratigraphsiche Reichweite dieser Dolomite reicht vom jüngeren Silur (Ludlow) bis in das Oberdevon [@Mavridis1969].\
+In der Einteilung der aktuellen Kartenblätter [@Heinisch1995; @Heinisch2003] und den Erläuterungen [@Heinisch2015] findet sich Der Begriff "Südfazies" nicht wieder. Vielmehr wurden Teile der Südfazies in die Spielbergdolomit-Gruppe übernommen und der erwähnte schwarze Dolomit wurde dem Dolomit-Kieselschiefer-Komplex zugeordnet. Auch in der aktuellen stratigraphischen Tabelle [@Hubmann2014] findet sich der Begriff Südfazies nicht wieder, sondern wird dort bei einigen Lithologien als Synonym geführt.\
+Insofern soll bei Arbeiten im Zuge dieses Projekts auch vom Begriff "Südfazies" Abstand genommen werden. Was aber für die Arbeiten hier durchaus Relevanz haben kannt, ist die Interpretation der unterschielichen Dolomite als riffogene Sedimente und Beckensedimente (\ce{SiO2}-führende Dolomite, Kieselschieferlagen, \dots).
+
+
+##  Tonschiefer
+Im Verband mit den Spielbergdolomiten treten gelegentlich Wechsellagerungen mit Tonschiefer auf. Im Hangenden der Plattformdolomite ist ein fliessender Übergang in diese feinstklastischen Sedimenten zu beobachten. Durch in diesem  Tonschiefer enthaltene Makroflorenreste, lässt sich deren Alter auf das Oberdevon oder jünger einengen [@Heinisch2015].
+
+## Kieselschiefer
+Assoziert mit den bankigen und massigen Dolomitfolgen der Spielbergdolomit-Gruppe können gelegentlich Wechselfolgen aus schwarzem, gebanktem Dolomit, Kieselschiefer (Lydit), Schwarzschiefer und grauem Tonschiefer auftreten. Diese Vorkommen können stratigraphisch an der Basis der Karbonatplattform eingeordnet werden, stellen aber auch Abscherhorizonte dar und  finden sich längs von Störungen oder in Schuppenkörper [@Heinisch2015]. Chronostratigraphisch wird diese Wechselfolge dem mittleren bis jüngerem Silur – mittleres Wenlock bis unteres Ludlow – zugeordnet und als ihr Ursprung wird eine tiefmarine Umgebung mit euxinischen Bedinungen  [@Hubmann2014] angesehen.\
+Der erwähnte schwarze Dolomit, soll hier besonders betont werden, ist er doch das Trägergestein der Magnesitmineralisation am Weißenstein.
+
+
+## Metabasite des Glemmtal-Komplexes
+
+Die Metabasite werden in den Karten als Metabasalt, Metatuff, Metatuffit und gabbroides und dioritisches Ganggestein ausgeschieden. Dies lässt auf eine gewisse Diversität hinsichtlich einer vulkanischen Genese schließen. Verglichen mit rezenten Vulkanprovinzen lassen sich Analogien zu Pillow- und Schichtlavastapel, unterschiedliche Varianten von basaltischen Pyroklastika, epiklasitischen Umlagerungen sowie subaquatischen Erruptionen mit unterschiedlichen Förderraten erkennen. Diese Vulkanite werden in mannigfaltiger Weise von gabbroidem Gestein intrutiert. Hierbei treten Lagergänge und vertikale Gänge sowie stockförmige Intrusionen auf [@Heinisch2015].\
+In Summe lassen sich diese Metabasite als ein mehrphasiger basischer Vulkanismus mit subvulkanitischen Intrusiva lesen. Detaillierte geochemische Untersuchungen durch @SchlaegelBlaut1990 konnten Zusammenhänge des Vulkanismuses mit aktiven Plattengrenzen -- sowohl ozeanische Rücken als auch Subduktionszonen -- ausschließen. Vielmehr lassen diese auf einen basischen Intraplattenvulkanismus schließen, der vulkanische Hochzonen (Seamounts, Inselvulkane) in einem wenig tiefen Randmeer darstellt.\
+Zusammenfassend werden diese Metabasite durch @Heinisch2015 als überwiegend flachmarine Seamounts interpretiert. Biostratigraphisch lässt sich dieses Geschehen, durch Conodonten, dem Unterdevon zuordnen und faziell wird im Glemmtal-Komplex eine Beckenfazies gesehen.\
+Geochronlogischen Datierungen dieser Gesteine mit der U/Pb- und Sm/Nd-Methode ergaben Alter im Bereich von \SIrange{492}{454}{\Ma} [@Heinisch2015 und dortige Referenzen]. Dies deckt ein breite Zeitspanne vom späten Kambrium bis in das mittlere Oberordovizium ab und ist im Wiederspruch zu obig genannten conodontenstratigrafischen Einordnung. Nach @Heinisch2015 muss diese Widerspruch als offen betrachtet werden. 
+
+**Anmerkung zur Gesteinsansprache**\
+Zu den oben erwähnten subvulkanitischen Intrusiva sei an dieser Stelle angemerkt, dass diese in der Literatur zum Teil als basaltisch-gabbroides Material und auch als Diabas(schiefer) zusammengefasst werden. Ersteres soll, vermutlich, den Übergangscharakter des Gefüges von Subvulkaniten zum Ausdruck bringen. Subvulkanite sind intrusive Gesteine, die durch Abkühlung und Auskristallisation unter der Erdoberfläche -- jedoch in geringerer Tiefe und mit meist geringerem Volumen als typische Plutonite -- entstehen. Ihre Feinkörnigkeit ist oft nicht so ausgeprägt wie jene der Vulkanite und sie leiten von den Vulkaniten zu den Plutoniten über. Diese relativ grobkörnigen basaltischen Gesteine, mit häufig intergranularem bis ophitischen Gefüge [@vinx2015gesteinsbestimmung], werden Dolerite oder Mikrograbbros (Korngröße über drei Millimeter) genannt. Der oft dafür synonym verwendete Begriff Diabas ist, aufgrund seiner Mehrdeutigkeit, zu vermeiden [@LeMaitre2002].

+# Magnesitvorkommen im Raum Hochfilzen, Ostalpen: Genetische Überlegungen {#sec-MgsGenetix}
+
+Weltweit sind die meisten wirtschaftlichen Magnesitvorkommen entweder dem kryptokristallinen oder dem Spatmagnesit-Typ zuzurechnen. Magnesit, der in sedimentären lakustrinen Milieus entsteht, spielt dagegen nur eine untergeordnete Rolle [@Pohl2020].
+
+Kryptokristalliner Magnesit (Kraubath-Typ, benannt nach einem Vorkommen in der Steiermark, Österreich) kommt als weiße und sehr feinkörnige Massen („bone magnesite“) gangförmig, stockwerkartig und massiv innerhalb (meta)ultramafischer Gesteine vor. Er ist das Produkt von Reaktionen bei niedrigen bis mittleren Temperaturen zwischen \ce{Mg}-reichen Gesteinen und \ce{CO2}-reichen wässrigen Fluiden hypogenen oder supergenen Ursprungs [siehe z.B., @Pohl1990]. Spatmagnesit (Veitsch-Typ, benannt nach einem stillgelegten Bergwerk in der Steiermark, Österreich) bildet unregelmäßige oft schichtgebundene Erzkörper, die bevorzugt in Karbonat dominierten Abfolgen eingeschaltet sind. Magnesit dieses Typs ist massiv, meist grobkristallin und weist oft spätige bis pinolitische Textur auf. Marine klastische bis karbonatische Schelfsedimente sind die häufigsten Ausgangsgesteine, die durch \ce{Mg}-reiche Fluide in einem Prozess umgewandelt werden, der als \ce{Mg}-Metasomatose bekannt ist. Metasomatische Verdrängungstexturen sind in diesen Lagerstätten weithin dokumentiert, aber das Alter der Magnesitbildung, die Art der Fluide, die Magnesiumquelle und die genauen Druck-, Temperatur- und chemischen Bedingungen (pTX) der Magnesit Bildung sind seit mehr als 150 Jahren umstritten. Historisch gesehen haben sich zwei Schulen entwickelt, die entweder epigenetische (metasomatisch-hydrothermale) oder syngenetische (sedimentäre bis frühdiagenetische) Modelle propagierten -- für ein Review siehe @Deelman2020.
+
+Die meisten Magnesitvorkommen in den Ostalpen sind Spatmagnesite und kommen in Karbonat dominierten paläozoischen Schichtfolgen in den tektonisch höchsten ostalpinen Einheiten vor; i.e., Veitsch-Silbersberger Deckensystem, Tirolisch-Norisches Deckensystem (geographisch Grauwackenzone) oder Deckenkomplex des Grazer Paläozoikums. Die Magnesitvorkommen und ihre Nebengesteine weisen häufig eine niedriggradige bis selten mittelgradige präalpine / alpine regionale Metamorphose auf.
+
+Die von RHI Magnesita in Österreich abgebauten Lagerstätten befinden sich in Breitenau (Steiermark), im Raum Hochfilzen (Tirol) und in Radenthein (Kärnten). Kleinere aktive Bergbaubetriebe anderer Unternehmen befinden sich in Oberdorf an der Laming und Hohentauern in der Steiermark. Die gesamte österreichische Magnesit-Jahresproduktion betrug im Jahr 2022 rund \SI{844000}{\tonne} [@MayerJauck2023].
+
+Die Magnesitvorkommen im Raum Hochfilzen liegen im Tirolisch-Norischen Deckensystem (geographisch „Nördliche Grauwackenzone“) und umfassen mehrere aktive und stillgelegte Bergwerke bei Weißenstein, Bürgl und Inschlagalpe. Diese Minen erstrecken sich über eine Länge von ca. 6 km in dem tektonisch komplexen Hochhörndler-Komplex (siehe @sec-lithoContents). Bei den karbonatischen Nebengesteinen handelt es sich hauptsächlich um Dolomit- und Kalksteine aus dem Silur bis Unterdevon. Frühere Studien unterschieden eine nördliche, von Riffen dominierte dolomitische Fazies (Unter- bis Mitteldevon, Spielbergdolomit) und eine südliche Fazies mit silurischen fossilführenden Kalksteinen bis frühdevonischen Dolomiten [@Mavridis1971] -- siehe auch @sec-suedfaz. Laut @Mostler1970 sind die Magnesitvorkommen auf die Südfazies beschränkt.\
+Es ist zu beachten, dass die Magnesitvorkommen in der „Nördlichen Grauwackenzone“ in unterschiedlichen Lithologien und in Karbonatsequenzen unterschiedlichen stratigraphischen Alters entstanden sind [@Mostler1973]. Daher sind sie nicht streng stratiform, sondern bestenfalls schichtgebunden. Die Magnesitvorkommen wurden durch eine niedriggradige Metamorphose der Grünschieferfazies überprägt, was durch Chloritoid, Pyrophyllit und Paragonit in den umgebenden Metapeliten angezeigt wird [@Morteani1989; @Morteani1990].
+
+Auf die räumliche Nähe der Magnesitvorkommen in der „Nördlichen Grauwackenzone“ zu tektonischen Deckengrenzen wurde bereits in früheren Untersuchungen hingewiesen [@Mostler1973; @Morteani1989]. Variszische Überschiebungen galten in einem metamorph-metasomatischen Modell als mögliche Fluidwege für die Mg-reichen mineralisierenden Fluide. In diesem metamorph-metasomatischen Modell wird die metasomatische Umwandlung von Dolomit in Magnesit durch einen inversen Temperaturgradienten aufgrund tektonischer Überschiebung und die Freisetzung von \ce{Mg^2+}-reichen Fluiden aus der überschobenen Einheit gesteuert [@Morteani1989; @Morteani1990]. Die Seltenerdelement (SEE) Gehalte und Muster von Magnesit im Vergleich zu denen der metasedimentären Karbonat-Wirtsgesteine stützen diese Interpretation [@Morteani1982].
+
+Magnesit aus dem Steinbruch Weißenstein ist makrokristallin, ihm fehlt jedoch die für viele andere Lagerstätten typische cm-große spätige Textur. Bei feinkörnigerem Magnesit ist selten noch eine Bänderung erhalten. Sie wurde als Relikt eines älteren Sedimentgefüges interpretiert, was auf eine initiale sedimentäre Magnesitbildung vor der anschließenden metamorphen Rekristallisation hinweist [@Vavtar1976; @Schulz1989].
+
+Magnesit wurde auch aus der permischen Gröden-Formation (Rotsedimente) gemeldet, die transgressiv über den frühpaläozoischen Schichten liegt, in denen sich die Spatmagnesitvorkommen von Hochfilzen befinden. Diese permischen Magnesite kommen als Knollen, in diskreten Schichten innerhalb von Tonsteinen sowie als intergranularer Zement vor [@Spoetl1994]. Magnesit in diesen Rotsedimenten bildete sich diagenetisch in einem Playa-Lake-System und das Magnesium stammte aus der Verwitterung devonischer Dolomitgesteine und damit assoziierter Magnesitvorkommen [@Spoetl1994]. Magnesit wurde auch in der permischen Basalbrekzie (Brunnsink-Brekzie) dokumentiert [@Siegl1953; @Angel1955]. Diese Brekzie enthält Klasten mit Magnesit, die als Sedimentkomponenten interpretiert wurden und ein wichtiges Argument für die Alterseinstufung der Magnesitbildung als präpermisch (variszisch) lieferte [@Angel1955]. Detaillierte Texturbeobachtungen deuten jedoch darauf hin, dass die Magnesitbildung in dieser Brekzie tatsächlich erst nach der Ablagerung erfolgte [@Siegl1964; @Mostler1970]. Es bleibt eine interessante offene Frage, ob und wie die Spatmagnesitvorkommen im Raum Hochfilzen mit jenen in den permischen Formationen genetisch verknüpft sind.
+
+Einige Fortschritte in unserem Verständnis der Fluide, die an der Bildung Spatmagnesite beteiligt sind, stammen aus Crush-Leach-Analysen [@Prochaska2001]. \ce{Na}/\ce{Br} vs. \ce{Cl}/\ce{Br}-Diagramme, die mit dieser Methode erstellt wurden, zeigen, dass die Spatmagnesite am Ende des Meerwasser-Verdunstungstrends plotten, was darauf hindeutet, dass die salzreichen Fluide („Bittern brines“) aus stark verdunstetem Meerwasser stammen [@Prochaska2016]. Die wenigen konventionellen Flüssigkeitseinschlussstudien, die an Magnesit in den Ostalpen durchgeführt wurden, bestätigen, dass es sich bei den mineralisierenden Fluiden um salzhaltige wässrige Solen des \ce{H2O}-\ce{NaCl}-Systems handelt [@AzimZadeh2011]. Die durch Mikrothermometrie ermittelten Temperaturen scheinen den Metamorphosegrad der Einheiten widerzuspiegeln; das heißt die Flüssigkeitseinschlüsse haben zumindest teilweise eine metamorphe Reequilibrierung erfahren.

+Die Etablierung eines korrekten genetischen Modells für die ostalpinen Spatmagnesitvorkommen hängt essenziell von der Verfügbarkeit verlässlicher Altersdaten ab. Bisher liegen nur sehr wenige Altersdaten vor. Das genaueste Alter wurde in der Lagerstätte Breitenau bestimmt, wo die Magnesitbildung mit der \ce{Sm}-\ce{Nd}-Methode auf \SI{229.3 \pm 2.4}{\Ma} datiert wurde [@HenjesKunst2014]. Dieses Alter der mittleren bis oberen Trias schließt orogene Modelle (variszische, alpidische) der Magnesitbildung aus -- ein Konzept das in den historischen metasomatischen Modellen wiederholt vorgeschlagen wurde. Stattdessen muss die Bildung der Spatmagnesite im größeren geodynamischen Kontext des Zerfalls von Pangäa und der Bildung der Neotethys gesehen werden. Die Ausdünnung der Lithosphäre und der erhöhte Wärmefluss in der Kruste spielten dabei eine wesentliche Rolle.
+
+Es ist festzuhalten, dass für die Magnesitlagerstätten im Raum Hochfilzen weder moderne Flüssigkeitseinschlussstudien noch Altersdatierungen vorliegen. Beides wäre erforderlich, um ein solides genetisches Modell zu erstellen, dass sowohl die Grundlage für zukünftige Exploration bilden kann als auch bei der Interpretation von „Air-borne“ Daten von großem Nutzen wäre.

+
+# Gesteinsbeschreibungen
+
+Für einen ersten Eindruck sind im Folgend die, im Untersuchungsgebiet relevanten, Gesteinsbeschreibungen aus [@Heinisch2015] extrahiert. Weitere detaillierte Gesteinsbeschreibungen finden sich bspw. in [@Vavtar1976] und [@SchlaegelBlaut1990].\
+
+## Blasseneck-Porphyroid
+
+Lithologienummern (53 | 49) in Blatt (122 | 123)
+
+> "Im Gelände sind die hellen, eher grobbankig bis massig absondernden Gesteine gut kartierbar. Charakteristisch ist eine pastellgrüne bis gelbliche Farbe. Das porphyrische Gefüge ist je nach Durchbewegungsgrad perfekt erhalten oder auch stark überprägt. Die makroskopisch erkennbaren, mm-großen Porphyroklasten erweisen sich im Dünnschliff als Quarz und Alkalifeldspat. Idiomorphe Formen (Hochquarz), teils mit magmatischen Korrosionsbuchten, sind häufig. Alkalifeldspat zeigt generell Perthit-Entmischungen, wobei die einzelnen Domänen unterschiedlich stark serizitisiert sind. Plagioklas tritt nur untergeordnet auf und ist immer stark alteriert. Die Matrix besteht aus einem feinen Filz von Quarz, Albit, Serizit und gegebenenfalls Chlorit. Idiomorphe Zirkone beweisen den primär magmatischen Charakter. [...] 
+>
+> Für eine erste Gelände-Unterscheidung (der Lithotypen) ist der variable Gehalt an Fremdgesteins-Bruchstücken im Vergleich zu Phänokristallen geeignet. Auch fast kristallfreie dichte Porphyroidlagen, gelbgrün im Aussehen, sind unterscheidbar. Diese, ebenso wie geringmächtigere Lagen, sind in der Regel kräftig geschiefert und weisen auffällig silbrig glänzende Trennflächen, z.T. seifig erscheinende Absonderungsflächen auf.
+>
+> Im Idealfall, sondern die Gesteine jedoch grobblockig-gneisartig ab und bilden dann Geschiebelieferanten für Lokalmoränen (Wildseeloder). Sie lassen sich als Leitgeschiebe bis ins Alpenvorland verfolgen. [...] 
+>
+> Insbesondere am Wildseeloder lassen sich vulkanologische Details noch heute im Gelände nachvollziehen."
+
+## Spielbergdolomit-Gruppe
+
+Lithologienummern (44-47 | 42-44) in Blatt (122 | 123)
+
+>"Es handelt sich um Dolomitgesteine unterschiedlicher fazieller Ausprägung mit Mächtigkeiten von bis zu 600 m. Damit bildet sich eine typische Dolomit-Verwitterungslandschaft, die zunächst rundgeschliffen von den Gletschern, zu Schuttbildung neigt und nur schüttere Vegetation trägt. Die durchgängig auftretende Verkarstung zieht entsprechende Trockenvegetation nach sich. [...]
+>
+> Die Gesteine sind angewittert von grauer, meist aber rostbrauner Farbe und tragen gelegentlich Bewuchs durch Landkartenflechte. Im frischen Bruch erscheinen sie reinweiß bis zartrosa, gelegentlich auch hellgrau. Primäre Sedimentstrukturen sind äußerst selten, geschuldet der diagenetischen Umkristallisation und metamorphen Überprägung.
+>
+> Mineralogisch handelt es sich überwiegend um Dolomit mit Beimengungen von Ankerit oder Eisendolomiten. Dies verursacht die häufig rostbraune Verwitterungsfarbe. Kalzit tritt kaum auf. Die Korngröße bewegt sich von \SI{0.1}{\mm} bis \SI{1}{\mm}. Man kann die Gesteine daher als Dolomitmarmore bezeichnen. Grusiger Zerfall und Absanden sind bei dieser Korngröße häufige Sekundäreffekte."
+>
+> __Dolomit-Sandstein-Folge__ `#44`: "Gut gebankte Dolomite wechseln lagig mit Quarzsandsteinbänken und Tonschiefern ab. Auch innerhalb der Dolomitbänke sind mikroskopisch Quarzklasten festzustellen."
+>
+> __Gebankter Dolomit__ (`#45`): Zeigt "[...] Bankmächtigkeiten von \SI{2}{\m} bis zu Dezimeter Bankstärke. Letzterer Fall ist der häufigere. [...] In günstigen Fällen sind reliktische Sedimentstrukturen in Form von Laminiten erhalten [...]. In anderen Fällen finden sich Bruchstücke von Crinoidenkelchen und Crinoidenstielgliedern [...]".
+>
+> __Massiger Dolomit__ (`#46`): Dieser Dolomit "[...] sondert grobblockig ab. Karstschlotten sind häufig, ebenso wie Schrattenbildung. Eine unregelmäßige Klüftung ist häufig. Gelegentliche Relikte von Korallen [...]" können vorkommen.
+> 
+> __Roter Flaserdolomit, Flasermarmor mit violettem Tonschiefer__ (`#47`): Diese "[...] fallen durch ein intensives Farbspiel (weiß-violett), ihre cm-dicke Bankung und meist wellig-flaserige Struktur auf. [...] Der Gehalt an tonigem Material variiert stark, es kann sogar zu cm-dicken Tonschiefer-Zwischenlagen kommen. [...] Gelegentlich sind die violetten Tonschiefer auch sekundär gebleicht, so dass der Gesteinskomplex eine grüngraue Farbe erhält."
+
+**Anmerkung**: Der massige Dolomit kann, nach @Heinisch1995, Träger von Magnesitmineralisationen -- bspw. Lagerstätten Bürgelkopf und Inschlagalpe -- sein und ist deshalb hier von besonderer Bedeutung.
+
+## Tonschiefer im Verband mit Spielbergdolomit
+
+Lithologienummern (43 | 41) in Blatt (122 | 123)
+
+>"Graue Tonschiefer treten gelegentlich in Wechsellagerung mit Spielbergdolomit (43) auf (westlich „Platte“ Richtung Pletzergraben, Malernalm bei Kitzbühel). Sie entwickeln sich aber auch hangend mit sedimentärem Übergang aus den Plattformdolomiten. Ein entsprechendes Profil befindet sich am Wildseeloder, südlich
+Grießenbodenalm. Hier kann gezeigt werden, dass es sich um die jüngsten erhaltenen Sedimentfolgen der Wildseeloder-Einheit unter der variszischen Winkeldiskordanz
+handelt."
+
+## Dolomit-Kieselschiefer-Komplex
+
+Lithologienummern (49 | 46) in Blatt (122 | 123)
+
+>"Wechselfolgen aus Dolomiten, Kieselschiefern, Schwarzschiefern und grauen Tonschiefern, die als Dolomit-Kieselschiefer-Komplex (49) zusammengefasst werden. [...]
+>Häufig fungieren sie [...] als Abscherhorizonte und finden sich längs von Störungen (u. a. Lämmerbichlalm) oder in Schuppenkörpern wieder (u.a. Lachtalbach, Römerweg-Barmleiten, Brunnalm, Jufenkamm).\
+>Gemeinsames Kennzeichen der Wechselfolge ist die schwarze Farbe, dem hohen Anteil an organischem Kohlenstoff geschuldet. Bis dm-gebankte, dunkle, zuckerkörnige Dolomite wechseln lagig im cm- bis dm-Bereich mit Lyditen und Schwarzschiefern ab. Auch graue Tonschiefer sind zwischengelagert. Die meist geringmächtige Folge bildet angesichts der auffälligen Färbung einen gut kartierbaren Leithorizont. Maximale Mächtigkeiten von bis zu 80 m sind bekannt. Angesichts der Neigung zu interner Kleinfaltung, Verschuppung und tektonischer Abscherung sind stratigrafisch ungestörte Profile jedoch sehr selten. Dies liegt u. a. am hohen Kompetenzkontrast zu den häufig benachbarten bankigen und massigen Dolomitfolgen."
+
+## Metabasalte des Glemmtal-Komplexes
+
+Lithologienummern (55, 57, 58, 59 | 50, 51, 52, 55) in Blatt (122 | 123)
+
+### Metabasalt, massig oder mit Pillowstruktur
+
+Lithologienummern (55 | 50) in Blatt (122 | 123)
+
+>"Metabasalte (55) sind in der gesamten Glemmtal-Einheit anzutreffen, wobei relativ häufig noch primäre Strukturen und Gefüge (Pillows, Blasen, Glasränder) erhalten
+sind. Zusammenhängende metamorphe Lavafolgen erreichen maximal 300 m Mächtigkeit. [...]
+>
+>Die Pillows zeigen Größen von maximal 1,5 x 1 m und minimal 0,3 x 0,1 m. Eine klare Variation der Pillowgröße vom Liegenden ins Hangende war in keiner der Abfolgen nachweisbar, hingegen ließ sich mehrfach ein Wechsel zwischen Schicht- und Pillowlaven feststellen. Aufgrund der konkaven Oberseite, der konvexen Unterseite und der Anpassung an die vorgegebene
+Morphologie an der Basis gut erhaltener Pillows ließ sich bei einigen Vorkommen eine stratigrafisch aufrechte Lagerung nachweisen. Dies stimmt mit den Ergebnissen aus den biostratigrafisch datierbaren Profilen überein. Die tektonische Überformung der Pillowstrukturen erschwerte in anderen Fällen eine Interpretation. Vereinzelt sind in den Metabasalten reliktische Glasränder erhalten. Diese erscheinen dicht, dunkelgrau bis schwarz und sind 1–3 cm breit. Das ehemalige Glas ist vollkommen devitrifiziert und zu einem feinen Saum aus Chlorit und Erzpigment umgewandelt.
+>
+>Makroskopisch lassen sich zwei Metabasalttypen unterscheiden. Beide kommen als metamorphe Pillowlaven und Schichtlaven vor. Dunkelgraue bis dunkelgrüne, unregelmäßig brechende Gesteine sind zum Teil als \"Diabasmandelstein\" ausgebildet; sie haben zahlreiche gefüllte Blasenhohlräume von durchschnittlich 0,3 cm Durchmesser. Hellgraue, sehr harte, splittrig und scharfkantig brechende Typen treten hingegen im vorderen Saalachtal auf (Blatt 123 Zell am See). Letztere zeigen einen geringeren Blasenanteil.[...]\
+>Die Dünnschliffuntersuchungen zeigen an Phänokristallen Pyroxen und Plagioklas sowie Pseudomorphosen nach Klinopyroxen, Orthopyroxen, Olivin und Plagioklas. In der Grundmasse sind Plagioklas, Hornblende, Chlorit, Epidot, Serizit, Kalzit, Leukoxen, Stilpnomelan, Klinozoisit und Quarz zu beobachten. Der Gehalt an Phänokristallen und deren Korngröße variieren sehr stark, wobei einsprenglingreiche und aphanitische Gefüge einander gegenüberstehen. Die Phänokristalle werden maximal 7 mm lang. Oft sind sie vollständig durch Sekundärminerale ersetzt."
+
+### Metatuff (pyroklastischer Vulkanit)
+
+Lithologienummern (59 | 55) in Blatt (122 | 123)
+
+>"Vulkaniklastische Gesteine können sowohl im Verband mit den Metabasalten als auch lagenförmig in den Metasedimenten auftreten. Es handelt sich um Vulkanitschiefer, die vielfach noch identifizierbare Komponenten führen. In Beispielen lässt sich die primär pyroklastische Natur der Komponenten z.B. als Lapilli oder Schlacken nachweisen. In anderen Fällen sind die Vulkanitbruchstücke eindeutig epiklastisch.
+>
+>[...]
+>
+>Der Löwenanteil der Pyroklastika findet sich in der Feinfraktion (Grobaschen- bis Feinaschen-Tuff). Diese liegen heute als stumpfgrün bis blaugrün erscheinende Vulkanitschiefer
+vor. Sie stellen den Hauptanteil der Aufschlussfläche, beispielsweise im Talschluss Glemmtal oder längs der Paß-Thurn-Straße südlich Jochberg. In der Regel zeigen sie eine deutliche Schieferung; gelegentlich massiger erscheinende Teile stellen ehemalige Grobaschen-Tuffe dar und sind leicht mit Schichtlavaströmen zu verwechseln. Mikroskopisch ist der Mineralbestand schlecht weiter auflösbar. Es handelt sich um einen feinen Filz aus Chlorit, Epidot, Albit und gelegentlich Kalzit. Feine Erzpigmentierung ist die Regel. Phänokristall-Relikte sind so gut wie immer metamorph umgebildet."
+
+### Gabbroide Ganggesteine
+
+Lithologienummern (57 | 51) in Blatt (122 | 123)
+
+>"Metamorphe gabbroide Ganggesteine (57) treten in der gesamten Glemmtal-Einheit diskordant in Gängen oder stockförmigen Massen und konkordant als Lagergänge auf (Mächtigkeiten häufig im Meterbereich, selten über 10 m bis zu maximalen Mächtigkeiten von etwa 100 m). Im vorderen Glemmtal ist ein enger Verband von gabbroiden Lagergängen und metamorphen basaltischen Laven charakteristisch [...]. In den übrigen Bereichen finden sich metamorphe Basalte und Metagabbros seltener in gemeinsamen Profilen. Konkordante und diskordante Gänge bzw. stockartige gabbroide Intrusivgesteine wurden hier innerhalb der metamorphen vulkaniklastischen Gesteine oder innerhalb der siliziklastischen Metasedimente kartiert[...]. Manche Gänge sind nur dm-mächtig. In diesem Fall können sie sehr leicht mit Grauwackenbänken verwechselt werden.
+>
+>[...] Das makroskopische und mikroskopische Erscheinungsbild der metamorphen gabbroiden Intrusiva ist sehr unterschiedlich. Im Aufschluss erscheinen diese Gesteine massig, dunkelgrün bis grau. Korngröße und Gefüge variieren über gleichkörnig (grob-, mittel- bis feinkörnig) zu porphyrkörnig mit maximal 1,5 cm langen Pyroxenkristallen. Schon im Handstück fällt eine hohe Variationsbreite im Gehalt an Pyroxen und Feldspat auf. Der mikroskopisch ermittelte Mineralbestand besteht hauptsächlich aus Klinopyroxen, Plagioklas, Hornblende, Epidot/Klinozoisit, Leukoxen und Stilpnomelan. An Akzessorien konnten Alkalifeldspat, Apatit, Titanit und Zirkon beobachtet werden. Am weitesten verbreitet sind subophitische Gefüge (Gesteine
+mit vorwiegend Pyroxen) und Intersertalgefüge (Gesteine mit überwiegend Plagioklas, Pyroxen dann als Zwickelfüllung, [...])."
+
+### Dioritisches Ganggestein
+
+Lithologienummern (58 | 52) in Blatt (122 | 123)
+
+
+>"Unter dem Arbeitsnamen dioritisches Ganggestein (58) sind Varianten mit einer Tendenz zu intermediärem Chemismus zusammengefasst. Diese Metadiorite sind vor allem [...] als Lagergänge bedeutsam. [...]
+>
+>Im Handstück erscheinen die Gesteine massig, meist feinkörnig bis dicht. Die Gesteinsfarbe zeigt ein Mittelgrau. Im frischen Bruch sind gelegentlich kleine Feldspatleisten
+zu erkennen. Damit werden sie in der Regel mit Grauwackenbänken verwechselt. Die lederbraune Verwitterungsfarbe und gelegentliche Pyritführung helfen jedoch im Gelände für eine richtige Zuordnung, die häufig durch Dünnschliffe bestätigt werden musste.
+>
+>Der mikroskopisch ermittelte Mineralbestand besteht hauptsächlich aus Plagioklas, Hornblende, Serizit, Chlorit, Pyroxen und Epidot. Quarz und Erz treten untergeordnet
+in Erscheinung. An Akzessorien sind Apatit und Zirkon zu beobachten. Hauptbestandteil des Gesteins sind hypidiomorphe, verzwillingte, zonar gebaute Plagioklasleistchen (etwa 1 mm Länge). Sie bilden ein sperrig regelloses Intersertal- bzw. Intergranulargefüge. Die Zwischenräume sind mit Erz, Serizit und Chlorit gefüllt; daneben treten kleine hypidiomorphe Hornblenden und vereinzelt Pyroxene auf. Quarz ist ebenfalls Bestandteil der Zwickelfüllungen. Es ist nicht klar zu entscheiden, ob es sich um primär magmatischen Quarz oder metamorphe Neubildungen handelt.
+>
+>Aufgrund der Nachbarschaft zu Gabbros werden die Gesteine als Differenziate interpretiert."
+
+
+## Magnesit
+
+Magnesit wird nicht in den geologischen Karten ausgeschieden. Aufgrund der zentralen Bedeutung für dieses Kartierungsvorhaben ist hier die Beschreibung des im Untersuchungsgebiet vorkommenden Magnesits aus [@Vavtar1976] entnommen:
+
+>"Der Magnesit kommt in den verschiedensten Farbvariationen vor. Es gibt alle möglichen Übergänge von [...] rotgefärbtem über orang zu gelb bis dunkelbraun und grau gefärbtem Magnesit. Es lassen sich drei markantere Typen unterscheiden:
+> 
+>  1. Gelber bis graugelber Magnesit mit Pyrit, Goethit und Lepidokrokit.\
+>  2. Roter [...] Magnesit mit Hämatit und untergeordnet Pyrit.\
+>  3. Grauer bis schwarzer Magnesit mit Pyrit. [...]
+>
+>Aber nicht nur in der Farbe, sondern auch in der Härte unterscheiden sich die Magnesite. Massige, relativ harte sowie poröse, weichere Typen kommen nebeneinander vor.\ 
+>Verschiedene Faktoren sind für das unterschiedliche Aussehen der Magnesite bestimmend:
+>
+>_Färbendes Pigment_: Hämatitreiche Sericitlagen oder feinste Hämatitschuppen färben den Magnesit rot. Örtlich kann der Hämatit zu bänderungsparallelen Knollen angereichert sein. Pyritreiche Sericitlagen bewirken eine dunkelgraue Farbe der Magnesite. [...]
+>
+>_Verwitterung_: Durch Verwitterung des Pyrits über Lepidokrokit zu Goethit wird der Magnesit braun gefärbt.
+>
+>_Jüngere Magnesium-Mobilisation_: Entlang von Klüften läßt sich oft gelber Magnesit beobachten, der zum Teil ausgehend von solchen feinen Rissen in die Schichtung hineinreicht und dem Magnesit ein „wolkiges" Aussehen verleiht. Es handelt sich dabei um eine jüngere Mg-Mobilisation, da der sonst oft zu beobachtende lagige Korngrößenwechsel fehlt und diese Magnesite auch dort, wo sie durch pigmentierten Magnesit ziehen oder schichtparallel in diesen hineinreichen, völlig pigmentfrei sind.
+>
+>_Korngrößenwechsel_: Auch der rhythmische Wechsel der Korngröße kann eine Grau-Gelb-Bänderung der Magnesite hervorrufen. [...] Im rhythmischen Wechsel der Korngröße lassen sich aber keine polaren oder geopetalen Gefüge in Form vertikaler Kornsortierung feststellen."
+
+*Anmerkung*: Dem aktuellen Stand des Wissens zufolge, ist die schwarze Färbung auf einen hohen Anteil an organischem Kohlenstoff zurückzuführen.

+title: "MultiMiner Austria -- Mapping Hochfilzen"
+subtitle: Overview for geological mapping
+lang: en
+---
+
+# Introduction
+This is intended to serve as an introduction for the preparation of the geological mapping. The areas to be mapped are defined and a brief geological overview is presented. The study area is placed in a modern regional geological framework and the rocks most relevant for the mapping work are presented.
+
+As a base for a more in-depth familiarization, the explanations for sheet 122 Kitzbühl [@Heinisch2015] and especially the rich literature list there should be mentioned. A geological overview of the magnesite deposits near Hochfilzen is given by e.g. @Vavtar1976.
+
+Magnesite mineralizations are currently known in the Spielberg dolomite group and in the dolomite-radiolarite complex (see below). The known deposits, such as Weißenstein and Bürgl, are located in the Hochhörndler complex [@Heinisch2015].  Regarding the magnesite deposits in the study area, it should be mentioned that there is a discussion about their age and their genesis going back to the 19th century with significant differences of opinion. The inferred age of mineralization ranges from middle Silurian over Variscan to Alpidic and the spectrum of genesis models include primary-sedimentary, synsedimentary to early diagenetic to metasomatic. Also, there are different ideas about the origin of magnesium intake [@tollman1977geologie].\
+See also @sec-MgsGenetix on this topic.
+
+
+## Location of the study area
+Geographically, the study area is located about five to seven kilometers southwest of Hochfilzen -- see @fig-AOI_Overview. It is mostly located in the province of Tyrol and a small part is located in the province of Salzburg.
+
+![Location of the study area -- marked in red (base map: basemap.at)](Figs/Overview__AOI_inAustria.pdf){#fig-AOI_Overview}
+
+## Map sheets
+The areas to be mapped concern sheets 122 Kitzbühl [@Heinisch2003] and 123 Zell am See [@Heinisch1995]. Explanatory notes [@Heinisch2015] are available for the former map sheet. The boundary of the two map sheets in the study area is the, here approximately north-south oriented, Fieberbrunner Ache. The majority of the areas to be investigated are located on sheet 122.\.
+Mentionable "sheet edge faults" between these sheets are not known in the study area and are not of major importance here because no mapping area overlaps the sheets. Important lithologies have different numbers on the map sheets, but are named roughly the same.
+
+## Questions
+The basic concern of the mapping work is the magnesite mineralization. Accordingly, the focus is on geological parameters that can be assumed to be relevant as evidence for magnesite mineralization processes. Important geological features include contacts to the adjacent rocks, differences in grain sizes, faults, \dots\
+It must not be ignored that the study area will be investigated in the course of this project, with methods of earth observation (EO) and remote sensing (RS) and the results of the mapping work will be linked with the findings of these methods. In this respect, the field work should also take into account what a satellite or drone "sees" and thus, for example, not only nice outcrops should be examined, but also weathered rock.
+
+## Issues
+At this point a few words about the practical field work and its preparation:
+
+* Online, the regions and areas are shown with different map material at <https://ardigeos.geologie.ac.at/mumimap>.
+* The mapping areas can be obtained as GeoPackage through the link <https://rhea.geologie.ac.at/index.php/s/rUqqImMlXdzGAUl>.
+* The two map sheets can be obtained through the Tethys Research Data Repository, of Geosphere Austria, through the following links as PDFs and as GeoPackages:
+  * GK 122 Kitzbühl: <https://doi.tethys.at/10.24341/tethys.53>
+  * GK 123 Zell am See: <https://doi.tethys.at/10.24341/tethys.54>
+* The Geological Maps of the Republic of Austria 1:50,000 can be integrated into GIS programs as raster layers via the following WMS/WMTS link: <https://gisgba.geologie.ac.at/arcgis/services/image/AT_GBA_GK50/ImageServer/WMSServer?request=GetCapabilities>
+* WGS84, EPSG:4326, is to be used as the coordinate system for marking field points. This is the same coordinate system used by GPS devices.
+* The positions of points recorded by GPS must be checked with a GIS program and satellite images (e.g. the orthophoto layer of basemap.at) and corrected if necessary prior to further use.
+* Structural measurements are to be reported in (dipDirection, dip)-value pairs -- as they are provided by structure compasses after Clar -- and not in (strike, dip)-value pairs as it is still common in the Anglo-American area.
+* The use of 10\% of hydrochloric acid to distinguish magnesite from dolomite has not proved successful. This can be deceptive, as aragonite may also be present in part. Macroscopic identification of carbonates is more appropriate.
+* Sample labeling should not be done on the sample with a permanent or paint marker, rather the sample should be placed in a bag and the bag should be labeled. The reason is a possible spectral analysis on the sample in the laboratory and colors added by markers could make this analysis difficult or impossible.
+* For field work, the period June-July seems to be ideal, because here mostly a stable weather situation (especially July) prevails and the days are long. In August, precipitation is traditionally expected. In September, however, favorable weather conditions could arise again, although the days are already shorter at this time.
+
+
+# Regions and areas
+The areas to be mapped are located in a roughly west-east oriented strip south of Fieberbrunn and Hochfilzen with the active open pit Weißenstein roughly in the middle -- see @fig-mappingAreasOverview and @fig-mappingAreasOverview_GK. For (preliminary) structuring, the study area is divided into three regions and associated areas. These are now briefly described here -- from east to west and with decreasing priority.

+
+![Overview of mapping areas (base map: Geological Map Austria)](Figs/MappingAreas__Overview__GK.pdf){#fig-mappingAreasOverview_GK}
+
+
+## East Region
+Lies to the east of the active Weißenstein open pit and is the only one of the regions on map sheet 123. It is bounded by the former Bürgl open pit, to the west, and Inschlagalpe underground mine, to the east. Two varieties of magnesite can be identified in this region: One fine-grained and one coarse-grained.
+
+### Area 1
+East of the former Bürgl open pit resp. the eastern side of the Spielberggraben. This area should be easily accessible: Access via Burgeralm and parking there and on. After consultation with the landowners, it may also be possible to use the alpine path to the Kleberkopf saddle.\
+For parts of this area there is a detailed description and mapping by @Riedler2010.
+
+     
+### Area 2
+The area around the former mine site Inschlagalpe. Here, a well exposed area to the west of the former mine site is of great interest. (South)East of this, the terrain is quite steep and forested -- however mapping information exists from when the mine was in operation. A relatively coarse-grained magnesite with zero porosity is found here.\
+Access via the Schwarzleotal with parking at the show mine Leogang. Possibly, the private road behind the gate can be used after consultation with the landowner.
+
+
+### Area 3
+This is still vaguely defined. Here, laser scans should be consulted in order to identify potential outcrops. If none of them could be identified the southern border of the Spielberg dolomite should be followed.\
+Access via the Schwarzleotal with parking possibility at the Leogang show mine. Possibly, the private road behind the barrier can be used after consultation with the landowner.
+
+## Central Region
+This region is on the eastern edge of map sheet 122. It is the area to the west and north around the Weißenstein open pit.
+
+### Region 4
+This is an hiking area including the Blumenweg track and some via ferrata near the ridge in the north. Of great interest here is an outcrop of black dolomite and especially its contacts with the neighbouring rock. Furthermore, this is an area where the Glemmtal complex and the Hochhörndler complex are exposed and therefore more metabasites could be found here.
+
+### Area 5
+Along the roughly west-east oriented "ridge" at the Lärchfilzkogel down to the Hörndlingergraben.\
+Parking is possible at the Lärchfilzhochalm and in the Hördlingergraben.
+
+## West Region
+The region is located directly at the western connection to Central Region and on map sheet 122. 
+This region is intended for model verification of earth observation (EO) and remote sensing (RS). The EO shall first provide indications of possible magnesite mineralization, which will subsequently be searched for.\
+This region is characterized by the Pletzerbach and its tributaries, the Lengfilzenbach and Grubalm with Sulztalbach.
+
+### Area 6
+In this area Magnesite is known as rolled pieces in the bedload of the Pletzerbach creek. Their origin in the form of outcrops is not known and should be clarified if possible. In the north of the Pletzergraben mighty Spielberg dolomites are exposed. Especially their boundaries to the south are to be localized and worked on. The area is part of the Pletzergraben and should be mapped on both sides of the Pletzenbach.\
+This area has the lowest priority and should be mapped depending on possibilities.
+
+
+# Geological framework
+On the map sheets mentioned above, the study area is located in the Wildseeloder unit $\subset$ Grauwackenzone $\subset$ Upper Austroalpine. Small-scale contacts with the Glemmtal unit -- also graywacke zone -- and the Northern Calcareous Alps $\subset$ Upper Austroalpine occur.\
+
+This traditional nomenclature of geological units no longer corresponds to the current state of knowledge. According to modern tectonic nomenclature, the area under investigation is part of the Staufen-Höllengebirge nappe, which is assigned to the Tyrolian-Noric nappe system [@Schmid2004; @Heinisch2015; @Huet2019].\
+An overview tectonic map of the Eastern Alps is given in @fig-TectUnitsofEasternAlps_afterSchmid and @fig-EAlpsTectUnits shows a schematic diagram of the major tectonic units of the Eastern Alps and the incorporation of the Tyrolian-Noric nappe system into these units. The palaeogeographic position of the Austroalpine from Cambrian to Devonian is outlined in @fig-PagGeo__AA__RockyAT.\
+The lithostratigraphic division of Paleozoic rocks within the Staufen-Höllengebirge nappe [@Huet2019; @Huet2022] was based on the explanations of GK 122 Kitzbühl [@Heinisch2015]. Four complexes are distinguished, which correspond to Variscan tectonic units. From the footwall to the hanging wall, these are the following lithodemic units: Uttendorf complex, Glemmtal complex, Hochhörndler complex and Wildseeloder complex. These are unconformably overlain by Permomesozoic lithostratigraphic units.
+
+The metamorphic history of the Staufen-Höllengebirge nappe is poorly studied. In general, it is assumed that there is an increase in the degree of metamorphism from north to south [e.g. @SchlaegelBlaut1990; @Heinisch2015; @Rantitsch2009]. In general maximum greenschist facies pressure-temperature conditions can be assumed for the study area: Approximately in the range of \SIrange{350}{400}{\celsius} and pressures greater than \SI{3}{\kilo\bar} and less than \SIrange{4.5}{8}{\kilo\bar} [@SchlaegelBlaut1990; and references therein].
+In detail, however, it seems difficult to assign the deformations and metamorphism to the Variscan or the Eoalpid event [@Huet2019].\
+Based on data from illite crystallinity, the degree of graphitization, the presence of chloritoid and the Conodont Alteration Index (CAI), metamorphism in the (lower) greenschist facies is assumed to have occurred during the (Cretaceous) Eoalpidian event. \isotope[40]{Ar}/\isotope[39]{Ar} ages, from white mica fine fractions, in the \SIrange{115}{95}{\Ma} range indicate cooling of the rocks of the Staufen-Höllengebirge nappe and their exhumation during this event [@Schuster_etal_2004; @Heinisch2015; and references therein]. This metamorphism was again weakly overprinted by advective heat transport and circulating fluids during the course of the Alpine orogeny, in the Oligocene to Miocene [@Rantitsch2009].
+Variscan metamorphism is not documented in the study area; however, weak (lowermost greenschist facies) prealpine deformation and metamorphism is assumed [@Heinisch2015].
+This is consistent with \isotope[40]{Ar}/\isotope[39]{Ar} dating [@Panwitz2006] of detrital muscovites indicating Neoproterozoic ages (in the range \SIrange{600}{800}{\Ma}). The closure temperature of muscovite in the \ce{Ar}/\ce{Ar} system, \SI{390 \pm 50}{\celsius} [@Schaen2020], has thus not been (significantly) exceeded since that time.
+
+## Note {.unnumbered .unlisted}
+Regarding the terms "Greywacke Zone" and "Northern Calcareous Alps", it should be mentioned that these historical terms date from a time before today's understanding of the tectonic nappe structure of the Alps [@Schuster2015]. One can probably understand these terms as geological units - in the sense that they refer to rocks characteristic for them. However, they are not tectonic or lithostratigraphic units in the strict sense [@Huet2019].\
+The term graywacke zone describes a geographic unit [@Schuster2015] which represents an east-west oriented strip of Paleozoic rocks. This is several hundreds of kilometers long, extends roughly from Schwaz in Tyrol to Lower Austria at the margin of the Vienna Basin, and has a maximum width of about \SI{25}{\km} [@Heinisch2015]. Based on the spatial allocation, the Western and Eastern Grauwackenzone can be distinguished.\
+Thus, the term graywacke zone - and the accompanying subgroups such as northern, southern, western and eastern - should be seen as an informal term without stratigraphic and tectonic implications.

+# Rock types and lithological units  {#sec-lithoContents}
+Lithologically particularly relevant for the investigations here is the Wildseeloder complex, which is made up of Middle Ordovician metaignimbrite (Blasseneck porphyroid), Upper Devonian siliciclastics and various Silurian to Upper Devonian carbonate rocks (including the Spielberg dolomite group) [@Heinisch2015; @Huet2019].\
+Rocks of the Glemmtal complex and the Hochhörndler complex can occur primarily on the southern edges of the areas to be examined. The Glemmtal complex comprises mostly Early Paleozoic to Lower Carboniferous mudstone, siltstone, sandstone and conglomerate with a turbiditic origin with subordinate inclusions of Ordovician and Devonian metabasites and also locally occurrences of Blasseneck porphyroid and carbonate rocks [@Huet2019]. The Hochhörndler complex consists of a siliciclastic matrix with isolated carbonate and magmatic elements from the Wildseeloder complex and the Glemmtal complex and it probably represents a sequence with olistoliths and/or a tectonic zone [@Huet2019]. Hence, rock types of the neighboring complexes are present in the Hochhörndler complex as reworked components.
+
+In the map sheets, only the Wildseeloder and Glemmtal complexes are distinguished. These represent different facies with their specific lithologies. The Hochhörndler complex is implicitly to be understood as a "transition zone" -- in which the lithologies of the other two complexes are mixed.\
+For practical fieldwork, the rocks can be assigned to the complexes as follows (oral comm. Benjamin Huet):
+
+Wildseeloder Complex
+: Thick carbonates and metaignimbrite, almost no basites, almost no pelites
+
+Hochhörndler Complex
+: Isolated, small-scale bodies of basites, carbonates, porphyroids in a matrix of siliciclastics such as slates, quartzites, \dots\
+  In the geological maps, the Hochhörndler Complex can be recognized by the fact that units of the Wildseeloder Complex lie next to units of the Glemmtal Complex without faults in between.
+
+Glemmtal Complex
+: Basites in carbonates and siliciclastics
+
+
+Important lithologies are briefly described here and are summarized in stratigraphic divisions in @fig-lithoStrat_StaufenHoellen_Heinisch and @fig-LithStratModel_StaufenHoellen_Huet.
+
+## Blasseneck porphyroid
+In the study area, this porphyroid can be found, for example, at the Wildseeloder with a succession of up to \SI{600}{\m} thickness [@Heinisch2015]. It has been correlated with the Blasseneck porphyroid, named after the Styrian type locality, on the basis of lithological criteria and its stratigraphic location under the Llandovery [^Llandovery] limestones [@Hubmann2014].\
+This porphyroid is interpreted as a subaerial pumice-rich deposit, resulting from a pyroclastic density current that was washed into shallow sea basins. The volcanism is considered to be \ce{SiO2}-rich, alkaline rhyolitic to rhyolitic. Hence, the chemistry suggests an extensional regime based on the alkaline rhyolitic character. Therefore, it could have been rift-related magmatism, which led to a partial melting of the continental crust due to an increased heat flow [@Heinisch1981; @Heinisch2015].\
+More recent investigations which include U-Pb dating from zircons and studies on zircon systematics by @Blatt2013 show ages in the range of \SIrange{471}{461}{\Ma} and also suggest an interpretation of continental rifting. The paleogeographical position is assumed to be the northern edge of Gondwana.

+
+## Spielberg dolomite group
+This group forms the host rock of some deposits such as siderite, baryte, fahlore and - here of particular importance - magnesite.\
+These dolomites represent the most important summits in the study area and form a coherent mountain range from the Kitzbühlerhorn via the Wildseeloder, the Spielbergerhorn to the Inschlagalpe. The type locality of these dolomites, the Spielbergerhorn [@Hubmann2014], is one of the study area boundaries (Region 2, @fig-mappingAreasOverview and @fig-mappingAreasOverview_GK).\
+This rock group is interpreted as a Silurian-Devonian carbonate platform [@Blatt2013] - which is now dolomitized. An age classification based on macrofossil remains, albeit sparse and weakly metamorphic, of corals, crinoids, and occasional conodonts indicates a Lower to Upper Devonian age [@Heinisch2015; and references there].\
+The typical formation of a carbonate platform with reef complexes and a lagoon can be inferred from the rock and the fossil remains. The transition to the mainland can be seen from the inputs of clayey-sandy clastics, influences of which can be found in the upper part. The different facies manifest themselves in different forms in the dolomite rock. According to @Heinisch2015, a distinction can be made between:
+
+"Massenfazies" -- massive dolomite
+: Occasional coral relics indicate that this massive dolomite represents the reef facies of the carbonate platform
+
+"Bankfazies" -- banked dolomite
+: The transition from the "Massenfazies" to the "Bankfazies" is differse and thus the bank thickness varies from two meters (rarely) to decimeters (more often).\
+This facies or this dolomite outweighs the other dolomites of this group in terms of frequency of occurrence. Due to the thickness and extent of these rocks, an extensive (Devonian) carbonate platform is assumed.\
+Sedimentary structures are occasionally preserved as laminites seen as remnants of algal mats from the stillwater area of a lagoon facies. Furthermore, crinoid remains can occasionally be seen, which could represent a transition from reef debris facies to reef areas.
+
+"Flaserdolomit-Fazies" -- red "Flaserdolomit"
+: In the facies transition to the "Bankfazies", thinnly banked colored zones occur and layers of argillaceous slate up to centimeters thick can be observed. The red color of the "Flaserdolomit" can be seen as an aeolian input of desert dust.
+
+"Dolomit-Sandstein-Folge"
+: Banked dolomites alternate with quartz sandstone banks and clay slates. Quartz clasts have also been found within the dolomites. Together with the "Flaserdolomit", this sequence is interpreted as a terrigenous sedimentary input from an adjacent continent. In terms of facies, these two dolomites could represent the transition from the lagoon facies to the beach area.
+
+Overall, the Spielberg dolomite group represents a shallow water facies close to the coast on the northern edge of Gondwana [e.g. @Blatt2013; @Heinisch2015; and references there]. A sketch of such a possible deposition space is given in @fig-rimmedCarbonatplattform platform.
+
+![Sketch of a carbonate platform as the possible environment from which the Spielberg dolomite group emerged.

+
+
+### Südfazies {#sec-suedfaz}
+A term that appears in the (older) literature is the so-called "Südfazies", which goes back to @Mavridis1969. He divides the carbonate rocks, in the area between Wörgl in the west and Bischofshofen in the east [@Haditsch1970], into two facies for the first time: the "northern facies" and the "southern facies". These two facies were describes as both lithologically and stratigraphically distinct and separated by a somewhat west-east oriented fault. @Mostler1970 also saw a "dolomite barrier" between the northern Spielberg dolomite and the Südfazies. The term Spielberg dolomite was introduced for the northern facies and its stratigraphic range was defined as Emsian to Eifelian (upper Lower Devonian to lower Middle Devonian). The southern facies has been defined as an association of distinct dolomites (stratigraphically ranging from footwall to hanging wall): black dolomite, light gray dolomite and red "Flaserdolomit", and light to dark gray coarse sparry dolomite. The stratigraphic range of these dolomites extends from the Younger Silurian (Ludlow) to the Upper Devonian [@Mavridis1969].\
+In the classification of the current map sheets [@Heinisch1995; @Heinisch2003] and the explanations [@Heinisch2015] the term "Südfazies" is no longer in use. Rather, parts of the "southern facies" were included in the Spielberg dolomite group and the black dolomite mentioned was assigned to the Dolomit-Kieselschiefer complex. The term "Südfazies" is also not found in the current (revised) stratigraphic table [@Hubmann2014], but is mentioned there as a synonym for some lithologies.\
+Consequently, the term "Südfazies" should also be avoided when working on this project. However, what can be relevant for the work here is the distinction of the different dolomites as reef and basin sediments (\ce{SiO2}-bearing dolomites, siliceous slate layers, \dots).
+
+## Slate
+In association with the Spielberg dolomite, alternating layers of slate occur occasionally. In the hanging wall of the platform dolomite, a smooth transition into these very fine clastic sediments can be observed. Due to the macroflora residues contained in this slate, its age can be narrowed down to the Upper Devonian or younger [@Heinisch2015].
+
+## Radiolarite
+Associated with the banked and massive dolomite sequences of the Spielberg dolomite group, alternating sequences of black, banked dolomite, radiolarite (lydite), black slate and gray clay slate can occasionally occur. These occurrences can be assigned stratigraphically at the base of the carbonate platform, but also represent décollements and are found along faults or as small rock bodies [@Heinisch2015]. Chronostratigraphically, this alternation sequence is assumed to belong to the middle to younger Silurian -- middle Wenlock to lower Ludlow -- and its origin is considered to be a deep marine environment with euxinic conditions [@Hubmann2014].\
+The black dolomite mentioned above should be particularly emphasized here, as it is the (main) carrier rock of the magnesite mineralization at the Weißenstein.
+
+## Metabasites of the Glemmtal complex
+
+The metabasites are marked in the maps as metabasalt, metatuff, metatuffite, and gabbroic and dioritic dykes. This suggests some diversity in terms of volcanic genesis. Compared to recent volcanic provinces, analogies to pillow and sheet lava stacks, different variants of basaltic pyroclastics, epiclastic rearrangements and subaquatic eruptions with different production rates can be identified. These volcanics are variously intruded by gabbroic rocks. Here, sills and vertical dykes as well as stock-like intrusions occur [@Heinisch2015].\
+To sum it up, these metabasites can be interpreted as a product of multiphase basic volcanism with subvolcanic intrusives. Detailed geochemical investigations by @SchlaegelBlaut1990 were able to rule out connections between volcanism and active plate boundaries -- both oceanic ridges and subduction zones. Rather, they suggest a basic intraplate volcanism, which represents volcanic high zones (seamounts, island volcanoes) in a shallow marginal sea.\
+In summary, these metabasites are interpreted by @Heinisch2015 as mostly shallow marine seamounts. Biostratigraphically, this event can be assigned to the Lower Devonian based on conodonts. Furthermore, the Glemmtal complex is described as basin facies.\
+Geochronological dating of these rocks using the U/Pb and Sm/Nd methods yielded ages in the range of \SIrange{492}{454}{\Ma} [@Heinisch2015 and references there]. This covers a broad period from the late Cambrian to the middle Upper Ordovician and is in contradiction to the conodont stratigraphic classification given above. According to @Heinisch2015, this contradiction must be considered open.
+
+**Note on geological vocabulary**\
+Regarding the subvolcanic intrusives mentioned above, it should be noted that in the literature they are partly summarized as basaltic-gabbroid material and also as diabase (schist). The former is supposed to express the transitional character of the fabric of subvolcanics. Subvolcanites are intrusive rocks formed by cooling and crystallization below the surface of the earth -- but at shallower depths and usually with smaller volumes than typical plutonites. Their fine-grainedness is often not as pronounced as that of the volcanic rocks and they represent transition from the volcanic rocks to the plutonic rocks. These relatively coarse-grained basaltic rocks, often with an intergranular to ophitic texture [@vinx2015gesteinsbestimmung], are called dolerites or micrograbbros (grain size over three millimeters). The term diabase, which is often used synonymously, should be avoided due to its ambiguity [@LeMaitre2002].

+# Magnesite deposits in the Hochfilzen area, Eastern Alps: Genetic considerations {#sec-MgsGenetix}
+
+Worldwide, most economic magnesite deposits are either of the cryptocrystalline Kraubath type or the sparry Veitsch type. Magnesite formed in sedimentary lacustrine environments only plays a subordinate role [@Pohl2020].
+
+Cryptocrystalline magnesite of the Kraubath type (named after an occurrence in Styria, Austria) occurs as white and very fine-grained masses (bone magnesite) in veins, stockworks and massive bodies within (meta)ultramafic rocks. It is the product of low- to moderate-temperature reactions between \ce{Mg}-rich rocks and \ce{CO2}-rich aqueous fluids of hypogene or supergene origin [e.g. @Pohl1990]. Sparry magnesite of the Veitsch type (named after an abandoned mine in Styria, Austria) forms irregular to strata-bound bodies that are preferentially hosted in carbonate-dominated sequences. Deposits of this magnesite type are massive, commonly coarse-grained and often show a sparry to pinolitic texture. Marine clastic to carbonate shelf sediments are the most common precursor rocks which are transformed by \ce{Mg}-rich fluids in a process known as \ce{Mg}-metasomatism. Metasomatic replacement textures are widely documented in these deposits, but the timing, the nature of the fluids, the source of magnesium and the exact pressure, temperature and chemical (pTX) conditions of magnesite formation are a matter of debate since more than 150 years.\
+Historically, two schools evolved that either propagated epigenetic (metasomatic-hydrothermal) or syngenetic (sedimentary to early diagenetic) models -- for a review see @Deelman2020.
+
+Most magnesite deposits in the Eastern Alps are of the sparry Veitsch type and occur in carbonate-dominated Paleozoic formations within the tectonic highest Austroalpine geological, i.e., the Veitsch-Silbersberg nappe system, Tirolian-Noric nappe system (geographically “Greywacke Zone”), or the Graz Paleozoic nappe complex. The magnesite deposits and their country rocks commonly record low-grade to rarely medium grade pre-Alpine and Alpine regional metamorphism.
+
+The main deposits currently mined by RHI Magnesita in Austria are located at Breitenau (Styria), in the Hochfilzen area (Tyrol) and at Radenthein (Carinthia). Smaller active mining operations of other companies are located at Oberdorf an der Laming and Hohentauern in Styria. The total annual Austrian magnesite production in 2022 was about \SI{844000}{\tonne} [@MayerJauck2023].
+
+Magnesite deposits in the Hochfilzen area are situated in the Tirolian-Noric nappe system (geographically “Northern greywacke zone”) and include several active and abandoned mines at Weißenstein, Bürgl, and Inschlagalpe. These mines stretch along a ca. \SI{6}{\km} long corridor that is associated to the tectonically complex Hochhörndler complex (see @sec-lithoContents). The carbonate host rocks are mainly dolostones and limestones of Silurian to Early Devonian age. Previous studies distinguished a northern reef-dominated dolomitic facies (Early to Middle Devonian Spielberg Dolomite) and a southern facies ("Südfazies") of Silurian fossiliferous limestones to Early Devonian dolostones [@Mavridis1971] -- see also @sec-suedfaz. According to @Mostler1970, the magnesite deposits are restricted to the southern facies.\
+It is to be noted that the magnesite deposits in the western “Greywacke Zone” formed in different lithologies and in carbonate sequences of different stratigraphic age [@Mostler1973]. Hence, they are not strictly stratiform but strata-bound, at best. The magnesite deposits have been affected by low-grade greenschist facies metamorphism as indicated by chloritoid, pyrophyllite and paragonite in the surrounding metapelites [@Morteani1989; @Morteani1990].
+
+The spatial vicinity of the magnesite deposits in the western “Greywacke Zone” to tectonic nappe boundaries was pointed out in previous studies [@Mostler1973; @Morteani1989]. Variscan thrust planes were thought to be possible fluid pathways for the \ce{Mg}-rich mineralizing fluids in a metamorphic-metasomatic model. In this metamorphic-metasomatic model the replacement of dolomite by magnesite is controlled by inversion of the temperature gradient due to tectonic overthrusting and influx of \ce{Mg^2+}-rich fluids from the overthrust unit [@Morteani1989; @Morteani1990]. The rare earth element (REE) contents and patterns of magnesite compared to those of the meta-sedimentary carbonate host rocks support this interpretation [@Morteani1982].
+
+Magnesite from the Weißenstein quarry is macrocrystalline but it lacks the cm-sized sparry magnesite texture that is typical for many other deposits. Banding is rarely preserved in finer grained magnesite. It has been interpreted as relict of an older sedimentary fabric whereby indicating an initial stage of sedimentary magnesite formation prior to subsequent metamorphic recrystallization [@Vavtar1976; @Schulz1989].
+
+Magnesite was also reported from the Permian Gröden Formation (redbed sediments), which unconformably overlie the Early Paleozoic strata hosting the sparry magnesite deposits in Hochfilzen area. These Permian magnesites occur as nodules, in discrete layers within mudstones as well as intergranular cement [@Spoetl1994]. Magnesite in these redbed sediments formed diagenetically in a playa-lake system and the magnesium was derived from weathering of Devonian dolostones and associated magnesite deposits [@Spoetl1994]. Magnesite was also documented in the Permian basal breccia -- Brunnsink breccia -- [@Siegl1953; @Angel1955]. This breccia contains magnesite-bearing clasts, which were interpreted as sedimentary components and provided a key argument for supporting the pre-Permian (Variscan) age of the magnesite formation in the Alps [@Angel1955]. However, detailed textural observations indicate that magnesite formation in this breccia is in fact post-depositional [@Siegl1964; @Mostler1970].\
+It remains an interesting question if and how the processes forming the sparry magnesite deposits in the Hochfilzen area and those in the Permian formations are genetically linked.
+
+Some progress in our understanding of the fluids involved in the formation of sparry magnesite deposits comes from crush-leach analyses [@Prochaska2001]. \ce{Na}/\ce{Br} vs. \ce{Cl}/\ce{Br} plots generated by this method reveal that sparry magnesites plot at the end of the seawater evaporation trend indicating that the saline fluids (“bittern brines”) derived from strongly evaporated seawater [@Prochaska2016]. The few conventional fluid inclusion studies done on magnesite deposits in the Eastern Alps confirm that the mineralizing fluids are saline aqueous brines belonging to the \ce{H2O}-\ce{NaCl} system [@AzimZadeh2011]. The temperatures obtained from microthermometry seem to reflect the metamorphic grade of the deposits (i.e., the fluid inclusions have undergone at least partial metamorphic re-equilibration).
+
+Establishing a correct genetic model for sparry magnesite deposits in the Eastern Alps strongly depends on availability of reliable age data. So far only a very limited number of age data is available. The most precise age was determined in the Breitenau deposit where magnesite formation was dated at \SI{229.3 \pm 2.4}{\Ma} with the \ce{Sm}-\ce{Nd} method [@HenjesKunst2014]. This Middle to Upper Triassic age invalidates models of orogenic (Variscan, Alpine) magnesite formation as repeatedly proposed in the historic metasomatic models. Instead, the formation of sparry magnesite deposits must be seen in the larger geodynamic context of lithospheric extension with enhanced crustal heat flow due to the break-up of Pangea and formation of the Neotethys.
+
+It must be stressed that neither modern fluid inclusion studies nor age data are yet available for the Hochfilzen deposits. Both would be required to establish a sound genetic model that could be the basis of future exploration and help in interpretation of airborne data.

+
+> "In the field, the light-colored, rather coarse-banked to massive protrude rocks can be mapped well. A pastel green to yellowish color is characteristic. The porphyry structure is perfectly preserved or also heavily overprinted depending on the degree of alteration and deformation. The macroscopically recognizable, mm-sized porphyroclasts are recognized in the thin section as quartz and alkali feldspar. Idiomorphic forms (high quartz), some with magmatic corrosion bays, are common. Alkaline feldspar generally shows perthite texture, with individual domains being sericitized to varying degrees. Plagioclase occurs only subordinately and is always strongly altered. The matrix is composed of a fine felt of quartz, albite, sericite and possibly chlorite. Idiomorphic zircons demonstrate the primarily magmatic character. [...]
+>
+> The variable content of xenolith fragments compared to phenocrystals can be used for a first field differentiation (of the lithotypes). Almost crystal-free, dense porphyroid layers, yellow-green in appearance, can also be distinguished. These, as well as thinner layers, are usually heavily foliated and have conspicuously shiny silvery discontinuities, some of which appear as soapy seperation surfaces.
+>
+> In the ideal case, however, the rocks crumble in a coarse-blocky and gneiss-like manner and then form detrital material for local moraines (Wildseeloder). They can be traced to the foothills of the alps as the main drift. [...]

+## Spielberg dolomite group
+
+Lithology numbers (44-47 | 42-44) in sheet (122 | 123)
+
+>"These are dolomite rocks of different characteristics in their facies with a thickness of up to 600 m. This creates a typical weathered dolomite landscape, which is initially rounded off by glaciers, tends to form debris and only supports sparse vegetation. The karstification that occurs throughout leads to corresponding dry vegetation. [...]
+>
+> The rocks are greyish when weathered, but mostly rust-brown in colour, and are occasionally covered with map lichen. Freshly broken, they appear pure white to pale pink, occasionally also light grey. Primary sedimentary structures are extremely rare due to diagenetic recrystallization and metamorphic overprinting.
+>
+> Mineralogically, it consits predominantly of dolomite with admixtures of ankerite or iron-rich dolomites. This causes the weathering color, which is often rusty brown. Calcite rarely occurs. The grain size ranges from \SI{0.1}{\mm} to \SI{1}{\mm}. The rocks can therefore be described as dolomite marble. Gritted decay and sanding are common secondary effects within this grain size."
+>
+> __Dolomit-Sandstein-Folge__ `#44`: "Well bedded dolomite alternates in layers with quartz sandstone beds and slates. Microscopic quartz clasts can also be found within the dolomite beds."
+>
+> __Banked Dolomite__ (`#45`): Shows "[...] bank thicknesses from \SI{2}{\m} to decimeter bank thickness. The latter case is the more common. [...] In favorable cases there are relict sedimentary structures preserved in the form of laminites [...]. In other cases, fragments of crinoid calyxes and crinoid stalk segments are found [...]".
+>
+> __Massive Dolomite__ (`#46`): This dolomite "[...] segregates in coarse blocky. Karst vents are common, as is striation. Irregular fracturing is common. Occasional relics of coral [...]" may occur.
+>
+> __Red Flaserdolomit, Flasermarmor with violet slate__ (`#47`): These "[...] stand out because of their intense play of colors (white-violet), their cm-thick banks and their mostly wavy, flaky structure. [... ] The content of clayey material varies greatly, there can even be cm-thick slate interlayers. [...] Occasionally, the violet slates are also secondarily bleached, giving the rock assemblage a green-grey colour."
+
+**Note**: According to @Heinisch1995, the massive dolomite can be a carrier of magnesite mineralization -- e.g. deposits Bürgelkopf and Inschlagalpe -- and is therefore of particular importance.

+Lithology numbers (49 | 46) in sheet (122 | 123)
+
+>"Alternating sequences of dolomites, radiolarite (lydite), black shale and gray slate, which are summarized as the Dolomit-Kieselschiefer complex (49). [...]
+>They often function [...] as décollement and can be found along faults (e.g. Lämmerbichlalm) or in rock slices (e.g. Lachtalbach, Römerweg-Barmleiten, Brunnalm, Jufenkamm).\
+>The common characteristic of the alternation is the black colour, due to the high proportion of organic carbon. Banked up to decimeters, dark, sugar-grained dolomite alternates in layers in the cm to dm range with lydites and black shales. Gray slates are also intercalated. In view of the perculiar colouration, the usually thin sequence forms a well mappable guiding horizon. Maximum thicknesses of up to 80 m are known. However, given the tendency for internal small folding, thrust tectonics and décollement, stratigraphically undisturbed profiles are very rare. This is due to the high contrast in consistency to the often neighboring banked and massive dolomite sequences."
+
+
+## Metabasalts of the Glemmtal complex
+
+Lithology numbers (55, 57, 58, 59 | 50, 51, 52, 55) in sheet (122 | 123)
+
+### Metabasalt, massive or with a pillow structure
+
+Lithology numbers (55 | 50) in sheet (122 | 123)
+
+>"Metabasalts (55) can be found in the entire Glemmtal unit, with primary structures and fabrics (pillows, bubbles, glass edges) commonly preserved. Connected metamorphic lava sequences reach a maximum thickness of 300 m. [...]
+>
+>The pillows show sizes of maximum 1.5 x 1 m and minimum 0.3 x 0.1 m. A clear variation of the pillow size from the footwall to the hanging wall was not detectable in any of the sequences, however, multiple shifts between layered and pillow lavas can be observed. Due to the concave top, convex bottom and adaptation to the predefined morphology at the base of well-preserved pillows stratigraphically direction in some places can be shown. This agrees with the results from the biostratigraphically datable profiles. In other cases, the tectonic reshaping of the pillow structures made interpretation difficult. Occasionally relict glass fragments   are preserved in the metabasalts. These appear dense, dark gray to black and are 1–3 cm across. The former glass is fully devitrified and transformed into a fine fringe of chlorite and ore pigment.
+>
+>Two types of metabasalt can be distinguished macroscopically. Both occur as metamorphic pillow lavas and layered lavas. Dark gray to dark green, irregularly breaking rocks are partly developed as "Diabasmandelstein" ("amygdaloidal diabase"); they have numerous filled bladder shaped cavities averaging around 0.3 cm in diameter. Light grey, very hard, splintery and sharp-edged types, on the other hand, occur in the lower Saalachtal (sheet 123 Zell am See). The latter show a lower proportion of bubbles.[...]\
+>The thin section investigations show pyroxene and plagioclase as well as pseudomorphoses after clinopyroxene, orthopyroxene, olivine and plagioclase as phenocrystals. Plagioclase, hornblende, chlorite, epidote, sericite, calcite, leucoxene, stilpnomelane, clinozoisite and quartz can be observed in the matrix. The content of phenocrysts and their grain size vary greatly, with phenocryst-rich and aphanitic textures present. The phenocrysts are a maximum of 7 mm long. They are often completely replaced by secondary minerals."
+
+### Metatuff (pyroclastic volcanic rock)
+
+Lithology numbers (59 | 55) in sheet (122 | 123)
+
+>"Vulcaniclastic rocks can occur both in association with the metabasalts and in layers in the metasediments. These are volcanic slate, which often still contain identifiable components. For example, the primarily pyroclastic nature of the components can be demonstrated, e.g. as lapilli or scoria. In other cases the volcanic fragments are clearly epiclastic.
+>
+>[...]
+>
+>The lion's share of pyroclastics is found in the fine fraction (coarse ash to fine ash tuff). These occure today as dull green to blue-green appearing volcanic slates. They make up the main part of the outcrop area, for example at the end of the Glemmtal valley or along the Pass-Thurn-Straße south of Jochberg. As a rule, they show clear foliation; parts that occasionally appear more massive represent former coarse ash tuffs and are easily confused with layered lava flows. Microscopically, the mineral composition is poorly resolvable. It is a fine felt of chlorite, epidote, albite and occasionally calcite. Fine pigmentation by opaque minerals is the rule. Phenocrystal relics are almost always metamorphically altered."
+
+### Gabbroid dykes
+
+Lithology numbers (57 | 51) in sheet (122 | 123)
+
+>"Metamorphic gabbroid rocks (57) occur unconformably as dykes or stock-like masses and concordantly as sills throughout the Glemmtal unit (thicknesses often in the meter range, rarely more than 10 m up to a maximum thickness of about 100 m). In the front part of Glemmtal a close association of gabbroid sills and metamorphic basaltic lavas is characteristic [...]. In the remaining areas, metamorphic basalts and metagabbros are found less frequently together. Concordant and discordant dykes or stocky gabbroic intrusive rocks were mapped within the metamorphic volcaniclastic rocks or within the siliciclastic metasediments[...] Some dykes are only dm thick, in which case they can easily be mistaken for greywacke beds.
+>
+>[...] The macroscopic and microscopic appearance of the metamorphic gabbroid intrusives is very different. In outcrop, these rocks appear massive, dark green to grey. Grain size and structure vary from uniform (coarse, medium to fine-grained) to porphyry-grained with maximum 1.5 cm long pyroxene crystals. A wide range of variations in the content of pyroxene and feldspar is noticeable even in the hand sample. The microscopically determined mineral composition consists mainly of clinopyroxene, plagioclase, hornblende, epidote/clinozoisite, leukoxene and stilpnomelane. Alkali feldspar, apatite, titanite and zircon could be observed as accessories. The most common are subophitic texture (rocks with predominantly pyroxene) and intersertal texture (rocks with predominantly plagioclase, pyroxene then as gusset filling, [...])."
+
+### Dioritic dykes
+
+Lithology numbers (58 | 52) in sheet (122 | 123)
+
+
+>"The term dioritic dykes (58) summarizes variants with a tendency towards intermediate chemistry. These metadiorites are especially significant as sills. [...]
+>
+>In hand sample, the rocks appear massive, mostly fine-grained to dense. The rock color shows a medium grey. Occasionally, small feldspar-slats are identified on the fresh fractured rock surface. As a result, they are usually confused with greywacke beds. However, the leather-brown weathering color and occasional pyrite leads to a correct assignment in the field, which often had to be confirmed by thin sections.
+>
+>The microscopically determined mineral composition consists mainly of plagioclase, hornblende, sericite, chlorite, pyroxene and epidote. Quartz and opaque minerals are subordinate in appearance. Apatite and zircon can be observed on accessories. The main components of the rock are hypidiomorphic, twinned, zonar plagioclase strips (about 1 mm long). They form a bulky irregular intersertal or intergranular structure. The interstices are filled with opaque minerals, sericite and chlorite; in addition, small hypidiomorphic hornblendes and isolated pyroxenes occur. Quartz is also part of the gusset fillings. It is not clear to decide whether it is primarily igneous quartz or metamorphic recrystallisation.
+>
+>Due to the proximity to gabbros, the rocks are interpreted as product of differentiation."
+
+## Magnesite
+Magnesite is not shown as a distinctive rock unit on the geological maps. Due to its major importance for this mapping project, the description of the magnesite occurring in the investigation area is taken from [@Vavtar1976]:
+
+>"Magnesite occurs in a wide variety of color variations. There are all possible transitions from [...] red-colored to orange to yellow to dark brown and gray-colored magnesite. Three more distinctive types can be distinguished:
+>
+> 1. Yellow to grey-yellow magnesite with pyrite, goethite and lepidocrocite.\
+> 2. Red [...] magnesite with hematite and minor pyrite.\
+> 3. Gray to black magnesite with pyrite. [...]
+>
+> The magnesites differ not only in color but also in hardness. Bulky, relatively hard as well as porous, softer types coexist.\
+>Various factors are responsible for the different appearance of the magnesite:
+>
+>_Colouring pigment_: Sericite layers rich in hematite or the finest hematite-scales color the magnesite red. Locally, the hematite can be enriched to nodules parallel to the lamination. Pyrite-rich layers of sericite cause the magnesite to have a dark gray color. [...]
+>
+>_Weathering_: The magnesite is colored brown by weathering of the pyrite via lepidocrocite to goethite.
+>
+>_Recent magnesium mobilization_: Yellow magnesite can often be observed along joints, which partly extends into the bedding from such fine cracks and gives the magnesite a "cloudy" appearance. This is a more recent magnesium mobilization since the layered change in grain size that is otherwise often observed is absent and these magnesites are completely pigment-free even where they penetrate pigmented magnesite or extend parallel into layers.
+>
+>_Grain size change_: The rhythmic change in grain size can also cause grey-yellow layering of the magnesite. [...] In the rhythmic change in grain size, however, no polar or geopetal sructure in the form of vertical grain sorting can be determined."
+
+*Note*: According to the current state of knowledge, the black coloring is due to a high proportion of organic carbon.

+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.
